[MIPS] Optimize JIT code generated by methods with TrustedImm32 operand

Source/WebCore:

Since r229828, we freeze the layer tree during the navigation policy check.
We freeze in WebFrameLoaderClient::dispatchDecidePolicyForNavigationAction()
and unfreeze in WebFrameLoaderClient::didDecidePolicyForNavigationAction().

WebFrameLoaderClient::dispatchDecidePolicyForNavigationAction() gets called
from PolicyChecker::checkNavigationPolicy() which has 3 call sites in
FrameLoader and one in DocumentLoader for redirects. The call sites in
FrameLoader were taking care of calling didDecidePolicyForNavigationAction()
on the FrameLoaderClient in their completion handler, but the DocumentLoader
call site was failing to do so. As a result, the layer tree would stay frozen.

To make this a lot less error prone, I moved the call to
WebFrameLoaderClient::didDecidePolicyForNavigationAction() to
PolicyChecker::checkNavigationPolicy(), inside the completion handler passed
to WebFrameLoaderClient::dispatchDecidePolicyForNavigationAction(). This way,
even if new code starts calling PolicyChecker::checkNavigationPolicy(), we
do not need to worry about letting the client know when the policy decision
is made.

No new tests, covered by existing redirection tests with the
new assertion I added.

Fixes an assertion failure when quiting an app that uses a Legacy WebKit web view
after dragging-and-dropping a PDF embedded using an HTML image element into the
same web view.

When performing a drag-and-drop of a PDF document image (WebCore::PDFDocumentImage) we create a WebArchive
from the main frame's WebHTMLView and promise AppKit that will provide a Rich Text Format (RTF) document
from this archive if needed. For some reason, on app termination AppKit requests that the WebHTMLView
fullfill its RTF document promise for the WebArchive created at the start of the drag operation. WebKit
expects that the created WebArchive is either for an inline image (e.g. <img>) or an image document that
has a supported image resource MIME type (by querying MIMETypeRegistry::isSupportedImageResourceMIMEType())
and checks for these cases in this order. PDF/PostScript are not listed in the set of supported image
resource MIME types. So, the first check fails and WebKit assumes that the WebArchive was created from
an image document of a supported image resource MIME type. However, the WebArchive was created from a
WebHTMLView and has MIME type text/html. Therefore the assertion fails. We need to add PDF and PostScript
to the set of supported image resource MIME types so that WebKit does not fall back to the WebHTMLView
code path. Historically, PDF and PostScript were in the set supported image resource MIME types. Over time
the set of MIME types for image resouces (images loaded as a document) became identical to the set of MIME
types for images loaded inline (e.g. <img>) and this set omitted the MIME types for PDF and PostScript.

Additionally it is sufficient to implement MIMETypeRegistry::isSupportedImageResourceMIMEType() in terms
of MIMETypeRegistry::isSupportedImageMIMEType() and MIMETypeRegistry::isPDFOrPostScriptMIMEType() instead
of allocating a dedicated HashSet for the supported image resource MIME types (as we currently do).

Source/JavaScriptCore:

Fixing this requires getting the ParserError (with information about the failure) and an ExecState* (to throw an exception) in the same place.
It is surprisingly painful, with quite a long call stack between the last function with an access to an ExecState* and the first function with the ParserError.
Even worse, many of these functions are generated by macros, themselves generated by a maze of python scripts.
As a result, this patch is grotesquely large, while all it does is adding enough plumbing to throw a proper exception in this specific case.

There are now bare calls to '.value()' on several paths that may crash. It is not a problem in my opinion, since we previously crashed in every case regardless of the path that took us to createExecutable when encountering a stack overflow.
If we ever find an example that can cause these calls to fail, it should be doable to throw a proper exception there too.

Two other minor changes:
- I removed BuiltinExecutableCreator.{cpp, h} as it was nearly empty, and only used in one place. That place now includes BuiltinExecutables.h directly instead.
- I moved code from ParserError.h into a newly created ParserError.cpp, as I see no need to inline functions that are only used when encountering a parser error, and ParserError.h is now included in quite a few places.

[Web Animations] Correctly obtain the timing function for a given keyframe
https://bugs.webkit.org/show_bug.cgi?id=184146

Reviewed by Dean Jackson.

Source/WebCore:

The way we would get the timing function for a given KeyframeValue stored in a KeyframeList was really suboptimal.
When keyframes were created, we would set the animated element's style on each keyframe, and set keyframe-specific
properties and values on top. When figuring out the timing function for a KeyframeValue, we would look at its render
style, go through its list of animations, which could include animations that are irrelevant to this specific keyframe
list since all animations from the animated element are referenced, and we would have to look up the correct animation
by name and get the timing function, even though the timing function stored on the animation was now specific to this
particular keyframe.

We now simply set a m_timingFunction member on a KeyframeValue, which is null if no explicit animation-timing-function
was provided for this keyframe in CSS, and otherwise set to a valid TimingFunction.

This fixes our behavior for a 4 existing animation tests when opted into the CSS Animations and CSS Transitions as
Web Animations feature.

Source/WebCore:

In the case where a FrameSelection updates its appearance when m_appearanceUpdateTimer is fired, the
FrameSelection's Frame is unprotected, and can be removed by arbitrary script. This patch applies a simple
mitigation by wrapping the Frame in a Ref when firing the appearance update timer, and ensuring that layout is
really up to date before calling updateAppearanceAfterLayoutOrStyleChange() from the timer.

Source/WebCore:

Align XMLHttpRequest's open() / send() / abort() with the latest specification:
- https://xhr.spec.whatwg.org

No new tests, rebaselined existing layout tests.

* xml/XMLHttpRequest.cpp:
(WebCore::XMLHttpRequest::open):
Align with https://xhr.spec.whatwg.org/#the-open()-method:
- Change the order of some steps to match the order in the spec. In particular,
  open() no longer resets the state to UNSENT or abort any existing load when it
  fails early due to being passed a bad method.

(WebCore::XMLHttpRequest::createRequest):
Align with https://xhr.spec.whatwg.org/#the-send()-method:
- Use the simpler "upload listener flag" logic from the spec instead of our more
  complex m_uploadEventsAllowed flag. This avoids constructing a SecurityOrigin
  objects on a background thread when XHR is used inside Web Workers, which was
  not thread-safe.
- Set the upload complete flag when the request has no body as per step 9.
- After firing the loadstartEvent, return early if the state is no longer OPEN or
  if the send flag is unset, as per step 11.3.

(WebCore::XMLHttpRequest::abort):
Align with https://xhr.spec.whatwg.org/#the-abort()-method:
- Only set the state to UNSENT if the state is still DONE after firing the error
  events, as per step 3.

(WebCore::XMLHttpRequest::didSendData):
Use new "upload listener flag".

(WebCore::XMLHttpRequest::dispatchErrorEvents):
Align with https://xhr.spec.whatwg.org/#request-error-steps:
- Stop firing a progress event in case of error as this is not as per specification
  and Firefox does not fire those either.
