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.

2791cd5a2c Allow inlining of named function expressions containing ThisFunction reference. 
Named function expression have an implicit local variable that
refers to the current function (ThisFunction). Before we only could inline
anonymous function expressions like:

A.prototype.foo = function() {}

as opposed to

A.prototype.foo = function foo() {}

This change enables inlining function of expressions like this.

e27d8fcbdc RegExpMacroAssembler::CheckStackGuardState should update input string pointer when it is moved or changed by GC. 
If input string was cons-string it might undergo short-circuiting during GC. This does not change input start if underlying seq-string (first element of cons-string) does not move but this makes input-string pointer on the native regexp's frame invalid.

1da890af54 Refactor how embedded pointers are visited. 
This refactoring (almost) gets rid of the requirement to get the target
object address for an object pointer embedded in code objects. This is
not possible on MIPS as pointers are encoded using two instructions. All
usages of RelocInfo::target_object_address() are (almost) obsoleted by
this change. The serializer still uses it, so MIPS will not yet work
with snapshots turned on.
