JavaScriptCore: DateInstance object collected on ARM JIT (JSValue: WTF_USE_JSVALUE32)

Part one.

Make some improvements to garbage collection code:

1) Fix the two classes that had the default mark bit set but

should not.

2) Remove checks of the mark bit outside the MarkStack::append

function; they are redundant.

3) Make more callers use the checked asCell and asObject

casting functions rather than unchecked casts.

4) Removed some GC-related functions because these operations are

no longer things that code other than the core GC code needs
to do directly. Fixed callers that were calling them.

  • bytecode/CodeBlock.cpp:

(JSC::CodeBlock::markAggregate): Removed unneeded check of the mark
bit before calling MarkStack::append.

  • interpreter/Register.h: Removed unneeded marked and markChildren

functions.

  • jit/JITStubs.cpp:

(op_eq): Removed unneeded assertions, instead using checked casting
functions such as asObject.

  • runtime/ArgList.h: Added now-needed forward declaration of MarkStack.
  • runtime/GetterSetter.cpp:

(JSC::GetterSetter::markChildren): Remmoved unneeded check of the mark bit.

  • runtime/GlobalEvalFunction.h:

(JSC::GlobalEvalFunction::createStructure): Added. Fixes a bug where the
HasDefaultMark bit was set.

  • runtime/JSCell.cpp:

(JSC::JSCell::getObject): Use asObject to avoid a direct static_cast.

  • runtime/JSObject.h:

(JSC::asObject): Added an overload for JSCell* and changed the JSValue
version to call it.
(JSC::JSValue::get): Use asObject to avoid a direct static_cast.

  • runtime/JSValue.h: Moved some stray includes that were outside the

header guard inside it. Not sure how that happened! Removed the
GC-related member functions markChildren, hasChildren, marked, and
markDirect.

  • runtime/JSWrapperObject.h: Made markChildren private.

(JSC::JSWrapperObject::createStructure): Added. Fixes a bug where the
HasDefaultMark bit was set. Later we may want to optimize this for
wrapper types that never have cells in their internal values, but there
is no measured performance regression in SunSpider or V8 doing this
all the time.

  • runtime/MarkStack.cpp: Tweaked formatting.

JavaScriptGlue: * JSValueWrapper.cpp:
(JSValueWrapper::JSObjectMark): Removed a check of the mark
bit. It's OK to do more work in this case, and there is no
longer a public function to access the mark bit.
