Original commit message:
Each SharedFunctionInfo gets an optimized code map to store
one optimized code object per context. When allocating a new
closure we consult this map and check if there is optimized code
that can be shared.

MIPS-specific changes:
-register codes and registers are defined using a macro to avoid redundancy
-renamed s8_fp to fp, removed the "fp" alias
-removed kSavedValueRegister (found by check-static-initializers.sh)

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 a

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
This CL also modifies the presubmit script to check the number of static initializers.

List of changes:
-added a minor optimization to the Simulator that quickly skips nops in the delay slot
-slightly re-worked CEntryStub to save a few instructions
CEntryStub now expects the following values:
-s0: number of arguments including receiver
-s1: size of arguments excluding receiver
-s2: pointer to builtin function
Two new MacroAssembler functions were added to make usage more convenient:
-PrepareCEntryArgs(int num_args) to set up s0 and s1
-PrepareCEntryFunction(const ExternalReference&) to set up s2
-removed branch delay slot nops from the most frequently used code areas
-reorganized some code to execute fewer instructions
-utilized the delay slot of most Ret instructions
This does not cover all Rets, only the most obvious cases.
Also added a special version of DropAndRet that utilizes the delay slot.
-added some comments to code areas where explanation of the register/delay slot usage may be needed
-added an optimization to Jump so it doesn't always pre-load the target register

CPU-eating DOS attacks against node.js servers. Based on code from
Bert Belder. This version only solves the issue for those that compile
V8 themselves or those that do not use snapshots. A snapshot-based
precompiled V8 will still have predictable string hash codes.
