Do not create handles for values of internal fields---this operation is performance
critical and plain pointers are safe.

Appy the same approach to External wrapping and unwrapping.

Plus some minor refactorings.

Hidden properties are used like internal fields which do not have
access checks. The checks can cause problems because there may be no
current context. See http://crbug.com/24200.

implementation is not yet complete (it prints only the node name for
some AST constructs) and does not serialize everything needed to
reconstitute the AST.

It is motivated by a desire to prototype source-to-source
transformations in JavaScript itself (or anything else that can grok
JSON), but it should have other uses too.

Feedback is welcome.

while, and for loops.

Previously they were distinguished by a type field, which required
runtime asserts to avoid invalid nodes (since not all loop types have
the same internal structure).  Now they C++ type system is used to
require well-formed loop ASTs.

Because they do not share compilation code, we had very large
functions in the code generators that merely did a runtime dispatch to
a specific implementation based on the type.

The calls to GenericBinaryStub can now pass the arguments in registers instead of on the stack. It is supported for ADD, SUB, MUL and DIV. The convention in GenericBinaryStub is not changed so the left operand is passed in edx and the right one in eax. When the stub contains smi code arguments are always passed on the stack as the smi code has to have left and right operands on eax and ebx, so moving from edx,eax to eax,ebx is not worth it and the smi code also trashes the registers so if arguments where passed in registers they would have to be saved on the stack anyway.

Added flags to disable the use of certain Intel CPU features to make it easier to test different code paths.

When starting JS profiling under Chromium, a map from function addresses to function names is created. During it, for sourceful scripts, an attempt to access script source is made. This can cause a crash, if a source is an external string, which already has been disposed. We had a similar problem in the past with DebugGetLoadedScripts.
