659e8f7b5c [compiler] Delay allocation of code-embedded heap numbers. 
Instead of allocating and embedding certain heap numbers into the code
during code assembly, emit dummies but record the allocation requests.
Later then, in Assembler::GetCode, allocate the heap numbers and patch
the code by replacing the dummies with the actual objects. The
RelocInfos for the embedded objects are already recorded correctly when
emitting the dummies.

2a78f2980b [x64] Do not compact constants with attached reloc info. 
Reloc info often means that the constant will be patched later, and for
this patching we have to make sure that there is enough space in the
code for the new value.

99230f8d0e [x64] Fix testw with immediates. 
Assembler::testw(Register, Immediate) and Assembler::testw(const Operand&, Immediate) were emitting only the first 8 bits of a 16-bit immediate, causing unexpected crashes.

This went unnoticed because before http://crrev.com/1948453002 no compiler was using them.

8dad78cdbd [turbofan] Add backend support for float32 operations. 
This adds the basics necessary to support float32 operations in TurboFan.
The actual functionality required to detect safe float32 operations will
be added based on this later. Therefore this does not affect production
code except for some cleanup/refactoring.

In detail, this patchset contains the following features:
- Add support for float32 operations to arm, arm64, ia32 and x64
  backends.
- Add float32 machine operators.
- Add support for float32 constants to simplified lowering.
- Handle float32 representation for phis in simplified lowering.

In addition, contains the following (related) cleanups:
- Fix/unify naming of backend instructions.
- Use AVX comparisons when available.
- Extend ArchOpcodeField to 9 bits (required for arm64).
- Refactor some code duplication in instruction selectors.

018ef484b9 More OStreamsUse OStreams more often. 
This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

fe243379f8 Decouple CpuFeatures from serializer state. 
Traditionally, we cross compile a snapshot iff the serializer is enabled.
This will change in the future.

Changes:
 - CpuFeatures probing is done once per process, depending on whether we
   cross compile.
 - CpuFeatures are consolidated into the platform-independent assembler.h
   as much as possible.
 - FLAG_enable_<feature> will only be checked at probing time (already the
   case for ARM).
 - The serializer state is cached by the MacroAssembler.
 - PlatformFeatureScope is no longer necessary.
 - CPUFeature enum values no longer map to CPUID bit fields.
