a2240fc52b Eliminate some virtual function from AST classes.
1. Remove unused dead functions.

2. Replace the virtual As-* type cast functions with non-virtual version
that uses node_type().

Result is around 13K reduction in binary size.

30465596e6 Make eval consider anything on the form eval(args...) a potential direct cal
Previously we omitted all cases where the global eval property was shadowed,
even if by a variable holding the same value. ES5 requires us to treat these
as direct calls.

We still throw if calling indirect eval with a detached global object.

0df252b38b Handlify the remaining CallStubCompiler functions.
Also, handlify functions for loading with interceptors and callbacks.
Remove some unneeded code.  Rename Foreign::address() because it
confusingly shadows HeapObject::address() which does something quite
different.

This fixes Date.prototyoe.toISOString to throw a RangeError exception
for invalid time values. It also includes a fix to removes the arbitrary

of a Date object. Note that we still have bogus range limits on the year

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.
