f74e723599 Initial infrastructure for fast compilation of top-level code. The 
fast code generator is optimized for compilation time and code size.

Currently it is only implemented on IA32.  It is potentially triggered
for any code in the global scope (including code eval'd in the global
scope).  It performs a syntactic check and chooses to compile in fast
mode if the AST contains only supported constructs and matches some
other constraints.

Initially supported constructs are

* ExpressionStatement,
* ReturnStatement,
* VariableProxy (variable references) to parameters and
    stack-allocated locals,
* Assignment with lhs a parameter or stack-allocated local, and
* Literal

This allows compilation of literals at the top level and not much
else.

All intermediate values are allocated to temporaries and the stack is
used for all temporaries.  The extra memory traffic is a known issue.

The code generated for 'true' is:

 0  push ebp
 1  mov ebp,esp
 3  push esi
 4  push edi
 5  push 0xf5cca135             ;; object: 0xf5cca135 <undefined>
10  cmp esp,[0x8277efc]
16  jnc 27  (0xf5cbbb1b)
22  call 0xf5cac960             ;; code: STUB, StackCheck, minor: 0
27  push 0xf5cca161             ;; object: 0xf5cca161 <true>
32  mov eax,[esp]
35  mov [ebp+0xf4],eax
38  pop eax
39  mov eax,[ebp+0xf4]
42  mov esp,ebp                 ;; js return
44  pop ebp
45  ret 0x4
48  mov eax,0xf5cca135          ;; object: 0xf5cca135 <undefined>
53  mov esp,ebp                 ;; js return
55  pop ebp
56  ret 0x4

1f8399bdda Partially revert r2761. 
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.

a563800b4c Initial implementation of printing the AST as a JSON string. This 
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.

586f94f292 Split the AST LoopStatement type into separate types for do/while, 
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.

8105ae3106 Optimize calls to GenericBinaryStub. 
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.
