f8db2414f2 Deprecate FACTORY helper macro.
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.

710c245a41 CPU profiler should support names of accessors set via v8::Object::SetAccessor
This change fixes the case when the accessors are invoked from JSObject::{Get,Set}PropertyWithCallback.

It already works for inlined calls generated by StoreStubCompiler::CompileStoreCallback. The same still needs to be fixed for getter invocations generated by  BaseLoadStubCompiler::CompileLoadCallback, corresponding case is commented out in the new test.

https://src.chromium.org/viewvc/blink?revision=151136&view=revision

this method can be deprecated and all the code that supports filtering
CPU profiles based on security origins can be later removed.

Drive-by fix: in line with CpuProfiler changes deprecated HeapProfiler::FindHeapSnapshot to reduce v8 API surface. FindHeapSnapshot may well be implemented based on existing GetSnapshotCount/GetSnapshot and it is only used in the tests.

The bug in the existing code was that it modified the |attributes|

But that affected any properties updated after an accessor property.
The code now sets up a mask each time and applies that instead of
mutating |attributes|.

3e41834721 Regexp parser: reset flag after scanning ahead for capture groups.
When the regexp pattern parser encounters an unbound reference to a
capturing group, it needs to scan ahead to decide whether it really
is a reference.  The scan advances to the end of the pattern string
and sets has_more_ to false, but fails to reset it to true so that
later on, parsing a character class wrongly fails.

36e91242fd Make Object.freeze fast
This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.

Relanding r14758 and r14759 with fix for Test262: only mark properties
and elements READ_ONLY if they are not JS setter/getters. Tightened up
tests to assert frozen-ness, and added targeted tests for the new code
(covering accessors).

Refactoring:
 * consistent use of SmiTag/Untag
 * added a few Smi macros and helpers
Improvements
 * small optimisations (e.g. merging untag and cmp #0)
 * added fixed point to double conversion instructions for simpler conversions

More on the last point: a Smi can be seen as a fixed point number with the
a one bit fractional part. Fixed to double instructions allow us to convert
a Smi to a double without untagging.

b1bd641078 Various minor cctest fixes to make ASAN a bit happier.
* Running with ASAN needs more stack, so don't set resource constraints too
     tight.

   * Checking boot time memory usage doesn't make sense when running with ASAN,
     it eats tons of memory for itself.

   * Fixed a malloc/delete[] mismatch: Not surprisingly, the pointer wrapped by
     a SmartArrayPointer should better be allocated by, well, NewArray...

Even with these 3 fixes, we still have a few failures when running our test
suite with ASAN. Most of them are either timeouts or failures caused by greatly
increased stack usage.

69c2f54d32 Skip samples where top function's stack frame is not setup properly
Stack iterator takes return address based on the frame pointer (ebp) and detects JS frames based on value at fp + StandardFrameConstants::kMarkerOffset. So in order the iterator to work correctly this values should be already setup for the current function. Stack frame is constructed at the very beginning of JS function code and destroyed before return. If sample is taken before before the frame construction is completed or after it was destroyed the stack iterator will wrongly think that FP points at the current functions frame base and will skip callers frame. To avoid this we mark code ranges where  stack frame doesn't exist and completely ignore such samples.

This fixes cctest/test-cpu-profiler/CollectCpuProfile flakiness.

8f602260d3 Implement yield* (delegating yield)
Ideally this would have been implemented via desugaring at parse-time,
but yield* is an expression, and its desugaring includes statements like
while and try/catch.  We'd have to have BlockExpression in the AST to
support that, and it's not worth it for this feature.

So instead we implement all of the logic in
FullCodeGenerator::VisitYield.  Delegating yield AST nodes now have a
try handler index, for the try/catch.  Otherwise the implementation is
straightforward.

3f09e0a3d8 Remove separate maps for function instances
ES3 specified that functions created via Function() would have
enumerable prototypes, unlike function literals.  For this reason, V8
has always had two prototypes for functions: "function_map" for
literals, and "function_instance_map" for "function instances": those
functions created by Function().

However, since 2009 or so, both maps have been the same!  Both have had
writable, non-enumerable prototypes.  Moreover, ES5 changed to specify
that function instances would have non-enumerable prototypes.

This patch removes the separate maps for function instances in sloppy
and strict mode.

885fd2f4b2 Fix yield inside with
This patch makes it so that suspending generators always saves the
context.  Previously we erroneously assumed that if the operand stack
was empty, that the context would be unchanged, but that is not the case
with "with".

Fixing this brought out an interesting bug in the variable allocator.
Yield inside with will reference a context-allocated temporary holding
the generator object.  Before the fix, this object was looked up in the
with context instead of the function context, because with contexts were
not being simulated during full-codegen.  Previously this was OK as all
variables would be given LOOKUP allocation instead of CONTEXT, but the
context-allocated temporary invalidated this assumption.  The fix is to
simulate the context chain more accurately in full-codegen.

71dc9e165f Capture receiver in generator object
Previously there has been no reason to context-allocate the receiver, so
access to the receiver always goes through the stack.  This was failing
with generators, which assumed that forcing context allocation would
relieve the need of storing anything but the context and the function on
the stack.

This CL adds a slot in generator objects to capture the receiver, and
restores it when resuming a generator.

Revert part of r14179. From the regression test's comment:

Currently, the gap resolver doesn't handle moves from a ConstantOperand to a
DoubleRegister, but these kind of moves appeared when HConstant::EmitAtUses
was changed to allow special double values (-0, NaN, hole). So we should
either enhance the gap resolver or make sure that such moves don't happen.

* src/ast.h:

  anticipation of boxing return values.  Parse `return' into `yield' in
  a generator.

* src/runtime.h:
* src/runtime.cc (Runtime_SuspendJSGeneratorObject): New horrible
  runtime function: saves continuation, context, and operands into the
  generator object.

* src/arm/full-codegen-arm.cc (VisitYield):
* src/ia32/full-codegen-ia32.cc (VisitYield):
* src/x64/full-codegen-x64.cc (VisitYield): Arrange to call
  SuspendJSGeneratorObject.  If the call returns the hole, we suspend.
  Otherwise we resume.

5206b08451 Remove code that analyzes tos values from tickprocessor
Assuming that the value on top of stack is return address for a frameless invocation is error-prone. Corresponding logic was removed from profile-generator.cc in r14205 (see https://code.google.com/p/v8/source/diff?spec=svn14205&r=14205&format=side&path=/branches/bleeding_edge/src/profile-generator.cc) and now it is time to remove it from the tick processor.

Since the tos is not used anymore by profiler it is also removed from TickSample.

75c388e691 Fix detection of indexed properties in Object.defineProperty()
When defining an indexed property on an Array object, the object's
length property should (perhaps) be updated.  This was done for any
property for which

  ToUInt32(name) == ToNumber(name)

was true, meaning any property name that, when converted to a number,
was an integer in the range [0, 2^32).  The detection should be more
strict; an indexed property is one for which

  ToString(ToUInt32(name)) == name

is true only.
