MIPS: Adapt Danno's Track Allocation Info idea to fast literals.

Port r13330 (6d9ce8a8)

Original commit message:
Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array, we store an AllocationSiteInfo object right after the JSArray, with a pointer to the boilerplate object. Later, if the array transitions we check for the continued existence of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to transition the boilerplate array as well.

Added %FlattenString and use it to speed up a regression test.

Flattening strings is relatively costly and by doing it after every duplication
we avoid combinatorial explosion.

Note that flattening could have been done by e.g. using a regular expression,
too, but this is just another implementation detail and %FlattenString seems
general enough to be useful in other tests, too.

Furthermore, the bookkeeping of the set is not measurable in all our benchmarks,

I'll rename NONE to NONE32 in a later CL.

This CL cleans up the RelocInfo::NONE usage by:
 - Using RelocInfo::IsNone when testing for NONE-ness.
 - Using NONE on 32-bit platforms (MIPS and IA32), and NONE64 on 64-bit
   platforms (x64).

This cleans up the code and prevents it from evolving bugs in the future
because NONE32 and NONE64 are used in misleading ways.

Use VLDR instead of VMOVs from GPR when a 64-bit double can't be encoded as a VMOV immediate.

This requires constant blinding before it can be enabled. There are other interesting optimizations that can be added later, detailed in a TODO.

Change is performance neutral but generates smaller code and encapsulates double alignment in the macro-assembler rather than at the allocation site.

This makes the DeoptimizeAll function O(n) instead of O(n^2) where n in the number of optimized functions.

Before this change, DeoptimizeAll iterated over the optimized function list and called DeoptimizingVisitor for each function. The visitor iterated over the optimized function list again to remove the functions that share the same optimized code.

This change partitions the optimized function list into one or more lists of related functions in one pass over the optimized function list.
