c74aae242a 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.

4e18d50834 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.

2531480d10 Re-establish mips basic infrastructure. 
This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.

All other mips arch files are replaced with stubbed-out versions that
will build.

Arch independent files are updated as needed to support building and
running mips.

The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

cdf65ca087 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.

45c63ffa6a Add more generic version of reloc info padding to ensure enough space for reloc patching during deoptimization (fixes issue 1174). 
The old version only added extra space when we did indirect calls, but
the problem remains the same with normal calls that can be represented
as a single byte. When doing patching each call will always be at
least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.

2. Added the ability to print objects to a specified file instead of

3. Added a use_verbose_printer flag (true by default) to allow some
   object printouts to be less verbose when the flag is false.
4. Fixed a bug in VSNPrintF() where it can potentially write into an
