5aafde9285 Print deoptimization index when printing lithium environment. 
Output of --trace-deopt --code-comments does not always allow to reliably match deoptimization to the lithium instruction (and it is actually never accurate on x64 due to one level of indirection). This change allows to reliably figure out which instruction deoptimized just by looking up bailout id in the hydrogen.cfg.

7b45ab9501 Don't use TLS for space iterators. 
This is not only inherently slow, but it also forces the caller to enter an
Isolate before. Both is bad, so we have to do some heap plumbing.

ec0b001543 Work around nifty VS10 compiler bug 
VS10 generates bogus code for specific arguments to the Number::New function when invoked in specific places of an ExpectRecords array definition, passing a garbage value to the function (as printf debugging reveals). Changing the argument from 1 to 7 apparently circumvents the problem.

3b08a1f82c Added new GetHeapStatistics API entry and deprecated old one. 
Simplified the HeapStatistics class a bit, following Uncle Bob's advice that
adding accessors to DTOs only satisfies some design fundamentalists, but serves
no other purpose. :-)

1e90596702 Simplify secure API functions workaround for MinGW 
If MINGW_HAS_SECURE_API is defined, the definitions of localtime_s,
fopen_s, _vsnprintf_s, strncpy_s had to be renamed using #define
so they would not conflict with definitions in the standard headers.

A simpler way to handle this is to undefine MINGW_HAS_SECURE_API before
including the standard headers.

f08b6ecac7 Split CompileCallConstant into logical parts for Frontend and Backend. 
Initial step towards separating IC (map check(s)), handler frontend
(prototype-check) and handler backend (actual handler code).

- Still need to split the map-check (IC) from rest of the prototype
  chain check.
- Still need to turn different parts in own code objects and cache them
  in more optimal places.

1c1fdc7da2 Better fix for MemoryChunk::owner(). 
Pointer arithmetic such as "owner_ - kFailureTag" is undefined behaviour
unless owner_ points to a valid object.

This allowed Clang to assume the subtraction would never be NULL,
causing problems in the caller (see https://codereview.chromium.org/12090072/).

To fix this, we should cast owner_ to intptr_t before doing the
arithmetic.
