fbc0a9cd6f Disentangle header dependecies a bit by moving PropertyDetails-related types into a separate header 
This moves PropertyType and its related predicate out of v8globals.h, where it didn't belong.

cd8d915c72 Clean up the marking speed heuristics. This reduces the 
max heap size on 64 bit from ca. 300Mbytes to ca. 200Mbytes
on Ulan's splay variant.  On 32 bit not much change.

2a1f08a1c2 Improve dominator computation to avoid worst-case quadratic time. 
In case of a degenerated CFG like in the example below processing
predecessors in the wrong order yields n^2 runtime.

  do {
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    // etc.
  } while (false);

Reversing iteration order avoids this.

36b715b1bd Refactoring only: Make the handling of PropertyType more explicit. 
Do not rely on 'default' clauses or 'if's when analysing a PropertyType, because
this makes it hard to find the relevant places when a new type is added. Note
that the detection of "phantom property types" is left untouched, because this
might have a performance impact, especially for the GC (to be investigated).

This is a preliminary step for introducing a new kind of map transition.

ea18539244 Tune context allocation for variables accessed from inner scopes. 
After introduction of with scopes we have enough static information to omit
context allocation in the case that a variable is accessed from a nested block
or catch scope of the same function. Only variables accessed from the inside of
a nested function or with scope are forced to be allocated in the context.

This essentially reverts

Specifically:
-fixed a bug in CompareAndSwap that caused randomly occuring timeouts on MIPS boards.
-added gcc inline asm control push/pop instructions to correctly save/restore the reorder setting instead of simply assuming it should be enabled.
-reordered/optimized some instructions to utilize MIPS-specific pipelining features (branch delay slot).
-fixed improper usage of write barriers

Also, handlify functions for loading with interceptors and callbacks.
Remove some unneeded code.  Rename Foreign::address() because it

e05c04e5fa Handlify CallStubCompiler::CompileCallField. 
This function relies on a number of helpers for checking prototypes and
probing dictionaries.  It is not possible to wrap these helpers to retry
after allocation failure in a safe way---the assembler has no way to undo
what it has already assembled.

These functions have all been duplicated with handle and raw versions.  The
raw versions will eventually be removed completely.

e8bccc2cb0 Block scoped const variables. 
This implements block scoped 'const' declared variables in harmony mode. They
have a temporal dead zone semantics similar to 'let' bindings, i.e. accessing
uninitialized 'const' bindings in throws a ReferenceError.

As for 'let' bindings, the semantics of 'const' bindings in global scope is not
correctly implemented yet. Furthermore assignments to 'const's are silently
ignored. Another CL will introduce treatment of those assignments as early
errors.

53e7502fa0 Fix bug in environment simulation after inlined call-as-function. 
This change is based on my previous change enabling inlining calls-as-function
fixing the bugs related to deoptimization.

The function value on top of the environment was dropped too late in the old code.
As a result we could get a wrong value on top after deoptimization.

This change includes r9619. It was reverted because of test failures that are fixed
with this patch.
