9d440fdd36 Store API callback entry address prior to entering a callback. 
Callback entry address is stored in VMState and is later retrieved by
profiler stack sampler. This makes possible relating API entry to JS
stack, and this is simpler than trying to unwind native stack.

a9d7c378d8 Add logging of callbacks in prof-lazy mode. 
This is needed to show calls to DOM in CPU profiles. I can think
of a better approach like adding specific functions into V8 API
for explicitly providing callback names and modifying bindings codegen
appropriately. My plan is as follows:
 - submit this CL;
 - implement anything I need to process log data and display DOM
   calls in profiles;
 - think again about adding specific functions and modifying bindings
   codegen.

d9d18b30f5 Implement IS_OBJECT and IS_FUNCTION as inlined runtime functions. 
Summary:
This change fixes a performance regression introduced by the special
handling of regular expressions in typeof expressions.
As a result we regain ~8% speedup on 3d-raytrace and ~13% on boyer
(vs bleeding edge)

Description:
The macros IS_OBJECT and IS_FUNCTION are frequently used in the 
JS runtime functions. 
By introducing new inlined runtime functions %_IsFunction and %_IsObject
we avoid invoking the more expensive %_ClassOf function plus comparing
its result to a string.

A callback on the debugger thread when a message is received. Allows the

53bee811ad Re-enable using push instructions for syncing the virtual frame. 
This change fixes the problem with the original version of this approach
(r3032) that may lead to a corrupted stack if we would invoke spilling during 
syncing a large SMI constant (unsafe SMIs) in the virtual frame.

The new code for storing unsafe SMI constants does not use an extra temporary 
register. This prevents the compiler from ever having to spill during a 
virutal frame sync operation.

For storing a large SMI constant we previously generated:

  mov ecx, (large_smi & 0x0000ffff)
  xor ecx, (large_smi & 0xffff0000)
  push ecx

we now generate:

  push (large_smi & 0x0000ffff)
  or   [esp], (large_smi & 0xffff0000)

Not using a temporary register avoids spilling within an nvocation 
of VirtualFrame::SyncRange.

Condition block of do/while statements is a valid break location so it should have its own position. The block is represented by a regular Expression node so we cannot store the position in it, instead the position is stored in a separate field in DoWhileStatement AST node.

1560b89888 Top-level compiler: Re-allow non-lazily compiled function literals. 
This change re-allows non-lazy compiled function literals for top-level compilation.

There was a problem on ARM exposed through this change which was fixed as part of r3289
in fast-codegen-arm.cc (Threading and Threading2 tests failed)

It occurred before r3289 when we allocate a local context at the beginning of a function. The
code for the stack check was split up in an unintended way (load of stack check limit into r2, 
and use of r2 in the actual stack check code).

ffda5f5ff5 Fixed bug in x64 port of KeyedStoreIC::GenerateExternalArray where it 
was always falling through to the runtime. Re-examined both load and
store ICs and verified they are now in sync with the 32-bit port.

Ran tests and benchmarks.
