This implementation extends the internal ObjectHashTable to be able to
hold arbitrary objects (e.g. Smis, Strings, ...) as keys by applying
specialized hashing functions to primitive types. Equality of keys is
defined using the internal SameValue function.

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.

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.
