[JS Bindings] prototype.constructor should be writable

<rdar://problem/22545096>

Reviewed by Darin Adler.

LayoutTests/imported/w3c:

Rebaseline W3C tests now that more checks are passing.

Source/WebCore:

prototype.constructor should have the following properties:
{ [[Writable]]: true, [[Enumerable]]: false, [[Configurable]]: true }

as per the Web IDL specification:
https://heycam.github.io/webidl/#interface-prototype-object

In WebKit, it is currently not writable. It is writable in Firefox.

This patch was first landed in r190085 but was rolled out for causing
crashes: <rdar://problem/22825602>. The issue was that even though we
marked constructor as writable, we failed to generate a setter for it.
This patch addresses the issue and the crash in <rdar://problem/22825602>
no longer occurs after this change. A regression test is also added for
this crash.

+        [JS Bindings] prototype.constructor should be writable
+        https://bugs.webkit.org/show_bug.cgi?id=149412
+        <rdar://problem/22545096>
+
+        Reviewed by Darin Adler.
+
+        prototype.constructor should have the following properties:
+        { [[Writable]]: true, [[Enumerable]]: false, [[Configurable]]: true }
+
+        as per the Web IDL specification:
+        https://heycam.github.io/webidl/#interface-prototype-object
+
+        In WebKit, it is currently not writable. It is writable in Firefox.
+
+        This patch was first landed in r190085 but was rolled out for causing
+        crashes: <rdar://problem/22825602>. The issue was that even though we
+        marked constructor as writable, we failed to generate a setter for it.
+        This patch addresses the issue and the crash in <rdar://problem/22825602>
+        no longer occurs after this change. A regression test is also added for
+        this crash.
