b93b2b98b8 Fix shared function info code replacement. 
This fixes a corner case when the unoptimized code for a shared function
info is replaced while the function is enqueued as a flushing candidate.
Since the link field is stored within the code object, the candidates
list got destroyed.

aee9febccc Some more instrumentation to narrow down Failure leaks. 
The basic idea is to tag OOM-Failure objects with an ID indicating where they were created. This requires changes to equality comparisons.

Note to MIPS folks: I'm planning to revert this CL in a couple of days, so feel free to skip porting the platform-specific changes.

9188bb67f2 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.

0aacbf9619 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.

eb9a22cc8b Environment bookkeping has linear time complexity now, not a quadratic one. 
This reduces the time take for mjsunit/limit-locals from 56.8s to 15.1s in debug
mode and from 12.0s to 1.6s in release mode.

Note that GrowableBitVector and BitVector should really be merged, and probably
have their allocation strategy parmeterized. The current state of affairs
involving tons of checks and delegation is extremely ugly, and it is far from
clear if all that special casing is a clear win. STL FTW! :-P

74026ea46d MIPS: Enable type feedback for branch statement and function call 
Port r13288 (5fa2c889)

Original commit message:
This change associates TypeFeedbackIds with ToBoolean stubs in
full-compiled code on ARM, allowing their information to be used in
Crankshaft. This eliminates unnecessary checks, especially in
DoBranch.

8a2cca5207 Replaced a bailout ID assertion with quadratic time complexity by a linear one. 
This reduces the time to run our test suite in debug mode considerably (from
8:43 to 4:05 on my local workstation using 32 threads). Note that the assertion
is so fast now that it doesn't need to be hidden behind --enable-slow-asserts.
Furthermore, the bookkeeping of the set is not measurable in all our benchmarks,
so I intentionally avoided any #ifdef chaos to keep things simple.

0606abbaab Rename RelocInfo::NONE to RelocInfo::NONE32. 
This CL only does renaming, nothing else.

Followup to:
https://chromiumcodereview.appspot.com/11695006/

There are now NONE and NONE64 RelocInfo types, but only ARM uses them
both at the same time. They were added in:

bb96439743 Cleanup RelocInfo::NONE usage. 
There are now NONE and NONE64 RelocInfo types, but only ARM uses them
both at the same time. They were added in:
  https://chromiumcodereview.appspot.com/11191029/

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.
