7a509f2101 Fix issue with running some constructors having only this.x = ... assignments. 
If we had compiled the comment instead of the code it would have worked.

ef95097334 Stop throwing exceptions for out-of-range accesses to CanvasArrays. 
This is per resolution in the WebGL working group to make these types
match the WebIDL IndexSetter and IndexGetter semantics, which are
still being defined but will very likely not throw.

d50fbb634e Fix bug that meant that dependent tests were never reported as 
failing (though they could still crash).
(Cache the result of the test in the output object, not in the
test object which is reused from the prerequisite to the dependent.)

d5f00cf6cc Add optimized ICs for new CanvasArray types introduced in WebGL 
specification under development. This is a follow-on CL to
http://codereview.chromium.org/293023 .

Based on review feedback, defined the behavior of storing NaN and
+/-Infinity into external arrays of integer types as storing 0. Added
test cases. Added fucomi instruction to assembler. Fixed bug in
KeyedLoadIC::GenerateExternalArray when allocation of HeapNumber
failed. Fixed bug in encoding of 16-bit immediate arithmetic
instructions in 64-bit port.

Removed raising of exceptions for negative array indices passed to
external arrays and associated tests. Based on current discussion in
WebGL working group, will probably end up removing the exception
throwing altogether.

fbc0eaa13d Added support for array literals to the toplevel compiler. They are 
currently compiled the same as with the optimizing compiler: they are
cloned from a boilerplate object and the boilerplate objects are
lazily constructed.

Also changed argument pushing on ARM to use stm (store multiple),
which required changing the order of arguments to the runtime
functions DeclareGlobals and NewClosure.  They were only used from
generated code.

Finally, changed the toplevel code generator so that stack pops to
discard a temporary became addition to the stack pointer on ia32 and
x64.

9ee631338e Allow resource constraints to specify the max committed new space size 
when using snapshots.

The alignment of new space has to match the alignment in the snapshot,
but the max committed amount of memory does not.

For now, we assume that the default semispace size is always used in a
snapshot.

46e6297e3e Added infrastructure for optimizing new CanvasArray types in WebGL 
specification under development. The optimizations are patterned after
those previously done for CanvasPixelArray. This CL adds all of the
necessary framework but continues to use the generic KeyedLoadIC and
KeyedStoreIC code, to create a baseline for benchmarking purposes. The
next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc.

These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of
being silently ignored.

As part of this work, pulled FloatingPointHelper::AllocateHeapNumber
up to MacroAssembler on ia32 and x64 platforms. Slightly refactored
KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
added a few more instructions that are needed for the new ICs. The
test cases in test-api.cc have been verified by hand to exercise all
of the generated code paths in the forthcoming specialized ICs.

When starting JS profiling under Chromium, a map from function addresses to function names is created. During it, for sourceful scripts, an attempt to access script source is made. This can cause a crash, if a source is an external string, which already has been disposed. We had a similar problem in the past with DebugGetLoadedScripts.

fb038bf146 Two changes, one a refactoring and one that affects V8's JS semantics. 
1. Change the AST node type CallNew to be a subclass of Expression
   rather than Call.  It's not really a call but it just happens to
   have the same fields.

2. Change our error reporting for invalid left-hand sides in for-in
   statements, pre- and postfix count expressions, and assignments.
   Before we signaled a syntax error at compile time *unless* the LHS
   was a function call or 'new' expression, in which case we signaled
   a reference error at runtime.  Now we signal a reference error at
   runtime in all cases.  This matches the JSC behavior in Safari 4.

70821329a5 Return the original value when assigning to a pixel array. 
After fast-case assignment to a pixel array the original value assigned is now returned. Before the un-tagged smi value was returned causing crashes.
