4246ac3009 Generalize calling to C++ on stub deopt 
Remove code specific to KeyedLoadICs in DoCompiledStubFrame on all platforms, driving stub frame translation by the register parameter information found in a stub's CodeStubInterfaceDescriptor.

4403daca1a ARM: generate integer zero in a uniform manner. 
ARM generated integer zero as either Operand(0, RelocInfo::NONE32), or
Operand(0), or Operand::Zero(). My change makes it use only
Operand::Zero().

This has no functional impact, it's pure cleanup.

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

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.

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.

a3f16f8e65 Fix several bugs in error stack trace formatting.
