106a477443 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.

This is a slightly modified version of r14915 which was rolled back due to test timeout on Windows. Compared to r14915 the new tests use OS::TimeCurrentMillis instead of OS::Ticks as OS::Ticks has ms precision on Windows and trying to wait 10 ticks (us) will result in at least 1 ms pause.

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.

515aec2014 Transforming PersistentHandleVisitor to not need to copy Persistent handles. 
This gets rid of more places where Persistent handles are copied
(see crbug.com/236290 ).

Transition plan: after this CL, Blink will be modified to work both with and
without the #define, then the #define will be removed from V8.

The corresponding Blink side changes are in https://codereview.chromium.org/15670010/ .

https://src.chromium.org/viewvc/blink?revision=151136&view=revision
https://src.chromium.org/viewvc/blink?revision=151196&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.

45ec481659 ARM: Smi refactoring and improvements. 
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.

d97fe8d4df Add Persistent::ClearAndLeak. 
This will be relevant after Persistent is changed to Dispose itself when
destructed. With Persistent::ClearAndLeak, Blink can take the ownership of the
object pointed by a Persistent and avoid it getting destructed.
