Landing for pliard@chromium.org: Remove static initializers in v8.
...
This change includes two CLs by pliard@chromium.org:
1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):
Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances are never deleted).
This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/
2. http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.
With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This static initializer populates a structure used by x86 atomic operations. It seems that we can hardly remove it. If possible, it will be removed in a next CL.
This CL also modifies the presubmit script to check the number of static initializers.

Remove the static qualifier from functions in header files.

This shaves 416+ KB, just under 1% off the size of the debug d8 executable
on Linux (mostly because the CheckHelper functions for assertions were
getting separate copies for each compilation unit). The difference in
release builds is negligible---a size reduction of 0.1%.
Also, change namespace-level 'static const' variables to remove the static
storage class as it's the default.

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.

MIPS: pre-crankshaft updates to code-stubs and stub-cache (3/3)
...
Highlights:
- code-stubs-mips.cc
-- use EmitFPUTruncate in place of inline code in several places.
-- use BranchF macro rather than lower-level FP cmp and branch for readability.
-- Port of Sven's r8859 (Implement type recording for ToBoolean) and r8886
(Simplify and optimize ToBoolean handling.)
-- Fix bug in TranscendentalCacheStub::Generate where some regs were not
saved across CFunction call.
-- use updated xxxCFunction macros.
-- update InstanceOfStub to support crankshaft
DoDeferredLInstanceOfKnownGlobal
-- Provide code-patching and I-cache flushing support for generated
code, used for InstanceOfStub under crankshaft (not submitted here).
This requires adding new ExternalReference to src/assember.cc,h
- stub-cache-mips.cc
-- port Danno's r8901 (Create a common base class for Fixed-, FixedDouble-
and ExternalArrays) to mips crankshaft branch.

Add constant splitting for user controlled constants in the full compiler
...
This is IA32 only for now.
Added a random value to each assembler instance (JIT cookie) to be used for constant splitting. Added safe versions of setting a register with an immediate value and for pushing an immediate value. Used these functions where user controlled immediate values could be emitted in the code stream. I also used it for immediates which are an argument number even though the number of formal arguments is currently limited to 16k.
I found no compares directly with user controlled constants.
I am not sure whether the test is that useful, but it might catch some changes missing constant splitting.

Remove some dead code.
...
- virtual-frame*
- register-allocator*
- jump-target*
- most of codegen*
- AstOptimizer and fields on AST
There is a lot of additional cleanup that we should do but this gets
rid of a lot.

Reimplement the padding of relocation information for lazy deoptimization on ia32.
...
The previous implementation attempted to keep track of the needed
relocation size for deoptimization while generating the optimized
code. That was error prone. This patch moves the relocation resizing
to the deoptimizer as the last step of creating an optimized code
object.
The down side to this approach is that two relocation information byte
arrays are created for all optimized functions that do not have enough
relocation space for lazy deoptimization.

Require an isolate parameter for most external reference creation to

avoid TLS access in connection with external references.
Make the isolate accessible via the assembler.
Only for ia32 at this point. If this looks OK to you I will port it.
