Remove concept of makeUsableFromMultipleThreads().
<https://webkit.org/b/141221>

Reviewed by Mark Hahnenberg.

Source/JavaScriptCore:

Currently, we rely on VM::makeUsableFromMultipleThreads() being called before we
start acquiring the JSLock and entering the VM from different threads.
Acquisition of the JSLock will register the acquiring thread with the VM's thread
registry if not already registered.  However, it will only do this if the VM's
thread specific key has been initialized by makeUsableFromMultipleThreads().

This is fragile, and also does not read intuitively because one would expect to
acquire the JSLock before calling any methods on the VM.  This is exactly what
JSGlobalContextCreateInGroup() did (i.e. acquire the lock before calling
makeUsableFromMultipleThreads()), but is wrong.  The result is that the invoking
thread will not have been registered with the VM during that first entry into
the VM.

The fix is to make it so that we initialize the VM's thread specific key on
construction of the VM's MachineThreads registry instead of relying on
makeUsableFromMultipleThreads() being called.  With this, we can eliminate
makeUsableFromMultipleThreads() altogether.

Performance results are neutral in aggregate.

Convert WebInspectorProxy to use WKWebView API for the inspector view
https://bugs.webkit.org/show_bug.cgi?id=141037

Reviewed by Timothy Hatcher.

Use the newer API for PLATFORM(MAC). The main difference is that the
WKWebView's page group cannot be set directly; instead, the group identifier
is passed. Also add some preference setters needed for the inspector.

Refactor some code to not use page groups directly. In a future patch,
the PageGroup-based inspector level system will be simplified. It is
it is no longer necessary to keep a static map of PageGroup instances,
since they are only used to save inspector window preferences. (These used
to prevent all levels of inspector from pausing together when a second-level
inspector hit a breakpoint. This is not necessary with multi-process
web inspectors.)

Also, adjust window resizing behavior when the inspector is docked to
the right. Window width resizes should not affect the width of the inspector
frame. This matches the behavior of height changes when docked to the bottom.

To support 32-bit Mac builds where WKWebView is not defined, share the stub
platformFoo() implementations with PLATFORM(IOS). The stubs are now located
in the platform-independent WebInspectorProxy.cpp.

Smart quoting could move the caret backwards in some configurations
https://bugs.webkit.org/show_bug.cgi?id=141203
Source/WebCore:

<rdar://problem/17452543>

Reviewed by Enrica Casucci.

The bug was caused by markAndReplaceFor not running the code to preserve the selection after
text replacement only when smart quote is enabled. Furthermore, when smart link was disabled,
we never applied smart quote due to the following condition at line 2502:

if (!(shouldPerformReplacement || shouldCheckForCorrection || shouldMarkLink) || !doReplacement)
    continue;

This condition prevented the code to apply smart quote from running when both continuous
spellchecking, smart link, and text replacement are disabled.

Fixed the bug by treating smart quotes and smart dashes like any other text replacement and set
shouldPerformReplacement to true whenever either one of those text checking options are present.

Smart link didn't have this issue due to the explicit check for shouldMarkLink.

Smart dashes didn't suffer this problem either because dashes replacement happens only once
the caret has moved past the dashes but his patch makes go through the same code path to preserve
the selection as well for consistency.

Convert WebInspectorProxy to use WKWebView API for the inspector view
https://bugs.webkit.org/show_bug.cgi?id=141037

Reviewed by Timothy Hatcher.

Use the newer API for PLATFORM(MAC). The main difference is that the
WKWebView's page group cannot be set directly; instead, the group identifier
is passed. Also add some preference setters needed for the inspector.

Refactor some code to not use page groups directly. In a future patch,
the PageGroup-based inspector level system will be simplified. It is
it is no longer necessary to keep a static map of PageGroup instances,
since they are only used to save inspector window preferences. (These used
to prevent all levels of inspector from pausing together when a second-level
inspector hit a breakpoint. This is not necessary with multi-process
web inspectors.)

Also, adjust window resizing behavior when the inspector is docked to
the right. Window width resizes should not affect the width of the inspector
frame. This matches the behavior of height changes when docked to the bottom.

arguments[-1] should have well-defined behavior
https://bugs.webkit.org/show_bug.cgi?id=141183

Reviewed by Mark Lam.

According to JSC's internal argument numbering, 0 is "this" and 1 is the first argument.
In the "arguments[i]" expression, "this" is not accessible and i = 0 refers to the first
argument. Previously we handled the bounds check in "arguments[i]" - where "arguments" is
statically known to be the current function's arguments object - as follows:

    add 1, i
    branchAboveOrEqual i, callFrame.ArgumentCount, slowPath

The problem with this is that if i = -1, this passes the test, and we end up accessing
what would be the "this" argument slot. That's wrong, since we should really be bottoming
out in arguments["-1"], which is usually undefined but could be anything. It's even worse
if the function is inlined or if we're in a constructor - in that case the "this" slot
could be garbage.

It turns out that we had this bug in all of our engines.

This fixes the issue by changing the algorithm to:

    load32 callFrame.ArgumentCount, tmp
    sub 1, tmp
    branchAboveOrEqual i, tmp, slowPath

In some engines, we would have used the modified "i" (the one that had 1 added to it) for
the subsequent argument load; since we don't do this anymore I also had to change some of
the offsets on the BaseIndex arguments load.

This also includes tests that are written in such a way as to get coverage on LLInt and
Baseline JIT (get-my-argument-by-val-wrap-around-no-warm-up), DFG and FTL
(get-my-argument-by-val-wrap-around), and DFG when we're being paranoid about the user
overwriting the "arguments" variable (get-my-argument-by-val-safe-wrap-around). This also
includes off-by-1 out-of-bounds tests for each of these cases, since in the process of
writing the patch I broke the arguments[arguments.length] case in the DFG and didn't see
any test failures.

JIT Compile simple cases of :nth-last-child()

Reviewed by Andreas Kling.

Source/WebCore:

This patch adds the code generator for :nth-last-child(), skipping
any :nth-last-child(An+B of selector list).

The code generator is boring here, nothing fancy.
There is no optimization opportunity here so it is basically the same
speed as the code generated by Clang when the simple selector is alone.

The only reason to JIT compile this is to avoid going to slow-path
for every selector that contain :nth-last-child().

The code creating the intermediate representation of :nth-child() is exactly

and share it for both simple selectors.

I fail :nth-last-child(An+B of selector list). Let's add it later.

Clean up attribute handling: part 2 - attributeNode
https://bugs.webkit.org/show_bug.cgi?id=141109

Patch by Benjamin Poulain <bpoulain@apple.com> on 2015-02-02
Reviewed by Andreas Kling.

Source/WebCore:

Our implementation was covering some old legacy behaviors of Firefox,
even copying bugs in some cases.

The spec (https://dom.spec.whatwg.org) now defines the behavior precisely,
let's move a bit closer to that.

Tests: fast/dom/Element/attribute-ascii-case-insensitive-3.html

       fast/dom/Element/setAttributeNode-overriding-lowercase-values.html

* dom/Element.cpp:
(WebCore::findAttrNodeInList):
New getter for the name-without-namespace case.

(WebCore::Element::setAttributeNode):
This one is the tricky one: https://dom.spec.whatwg.org/#dom-element-setattributenode

When setAttributeNode() is used with an AttributeNode without namespace,
getting the old value behaves like getAttribute(), with ASCII lowercase name matching.
When used with a namespace, getting the old value behaves like getAttributeNS().

Setting the value is a whole different story, the name used always keeps
the original case.

Now that's a bit tricky for us because AttributeNodes are just legacy stuff we don't
used internally.

We have 4 cases to handle:
1) The name being set is lowercase, there was no conflicting name on the element.
   That's easy, we just override any node that would exist, set the name otherwise.
2) The name is lowercase but there was an existing attribute for it.
   -We create a new AttributeNode for the name to represent the old name.
   -We check the names are the same with attribute.name().matches(attrNode->qualifiedName())
    and override the value.
3) The name has uppercase characters, there is no conflicting name.
   We would not find an element to remove, we just use setAttributeInternal() as usual
   to add the attribute;
4) The name has uppercase characters, there is a lowercase conflicing name.
   This is the weird behavior: we need to nuke the old attribute, then add the new attribute
   with a different case.

   First we remove the attribute with a lowercase name with removeAttributeInternal().
   That becomes the old node.

   There might still be an element of the same name as what we are trying to add. We don't want
   to add another version of the same attribute. We need to use findAttributeIndexByName() again
   to find if there is a conflicting attribute. Then we call setAttributeInternal() which handle
   the both the cases where there was an element or not.

This should work like any "NS" method.

[Cocoa] Make decoded image data purgeable ASAP.
<https://webkit.org/b/140298>
<rdar://problem/19623377>

Reviewed by Antti Koivisto.

Re-landing this patch since it turned out to not be the cause of
the memory regression we saw around that revision.

Mark decoded images as "transient" which makes CoreGraphics mark
the backing stores as purgeable shortly after they're used.

The decoded representation will remain in CoreGraphics's caches
indefinitely unless the kernel gets starved and needs the pages.

Most resources will now reach a state where the encoded data is
mmap'ed from disk cache (once the entire resource is downloaded)
and the decoded data is purgeable.

This also has the side effect of making the MemoryCache more
palatial since the decoded data cost can be deducted for images,
allowing us to cache more resources.

Note that the worst case for this new behavior would be something
like hovering below 100% memory utilization and constantly having
to drop and re-decode images. While churny, it still beats
crashing the process, plus there's tiling to remove many of the
reasons we'd need the decoded data.
