4e4a901d96 Remove the forward-bailout stack from the non-optimizing compiler. 
This was pretty heavyweight.  It was kept in just for a few corner cases
that assumed it was there.  We can work around them by making sure that the
expression in a reified test context is always really the expression that
was visited in that context; and by inspecting the context manually and
consing up a pair of extra AST IDs for the unusual case of unary not in a
value AST context.

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.

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.

e8a26d1eb1 Add write barrier helper for code patching and refactor stack check patching. 
The new helper avoids expensive FindCodeForInnerPointer invocation when we have
the host code object available. It is used when patching stack checks.

Also some comments on the ARM platform are corrected.

56c763f023 Make the GC aware of JSReceiver pointers in LookupResults. 
The LookupResult utility class is used in handlified code, but it can
contain a raw pointer to the lookup's holder object.  Create a per-thread
stack of live LookupResults and iterate all the live ones on GC.
