I also added a test for movdqa, which was already implemented.

New code should use nullptr instead of NULL.
This patch updates existing use of NULL to nullptr where applicable,
making the code base more consistent.

Since frames.h no longer defines basic register types like RegList, it
is no longer necessary to include it in the macro assemblers.
Next step: split out frame-constants.h from frames.h so that it will be
possible to get frame constants without include the stackwalking logic,
which needs objects.h.

Instead of auto-generating the Name() convenience accessor, use a macro to
avoid wasting code space.
BUILTIN_CODE(isolate, Name)
expands to
isolate->builtins()->builtin_handle(Builtins::kName);
This reduces the size of libv8.so by 134,752 bytes on a x64 release build.

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.

- Add I16x8 Splat, ExtractLane, ReplaceLane, shift ops, Some BinOps and compare ops
- Add pshufhw, pshuflw in the assembler, disassembler
- Fix incorrect modrm for pextrw, this bug disregards the register allocated and always makes pextrw use rax.
- Fix pextrw disasm to take the 0 - 7 bits of the immediate instead of 0 - 3.
- Pextrw, pinsrw are in the assembler use 128 bit encodings, pextrw, pinsrw in the disassembler use legacy encodings, fix inconsistencies causing weird code gen when --print-code is used.

Current implementation of the pextrw instruction is the legacy SSE2 instruction in the assembler (66 0F C5), and SSE4 implementation(66 0F 3A 15) in disasm-x64.cc, this causes incorrect instruction encodings to be printed when using --print-code flag for debug, in this case, causes over flow of bytes, and subsequent instructions to be incorrectly disassembled. Fixing to use SSE4 encodings in the assembler cosistent with pextrb, pextrd.

Previously, when restarting a frame, we would rewrite all frames
between the debugger activation and the frame to restart to squash
them, and replace the return address with that of a builtin to
leave that rewritten frame, and restart the function by calling it.
We now simply remember the frame to drop to, and upon returning
from the debugger, we check whether to drop the frame, load the
new FP, and restart the function.

The former will handle loads of predeclared global variables (vars and
functions), lets, consts and undeclared variables. The latter will handle
named loads from explicit receiver. In addition, named loads does not
depend of the TypeofMode.
TypeofMode related cleanup will be done in the follow-up CL.

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.
