62f929ff4c Use nullptr instead of NULL where possible 
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.

7d38ee3011 [iwyu] Do not include frames.h in macro assemblers. 
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.

2f79e03560 [builtins] Remove Builtins::Name() accessors 
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.

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.

3f47c63ded [liveedit] reimplement frame restarting. 
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.

479de28c3a Revert of Adding ia32 simd assembler changes. (patchset #2 id:20001 of https://codereview.chromium.org/1991713002/ ) 
Reason for revert:
Crashes on win32 debug:
https://build.chromium.org/p/client.v8/builders/V8%20Win32%20-%20debug/builds/2305/steps/Check/logs/stdio

Also, would be nice if the test output could be a bit shorter and only print what's necessary to trace a failure. Or split things into more smaller tests. Like that, these logs must be processed, json-encoded/decoded and sent around through the infrastructure.

Some chars in the output make the json encoder unhappy, therefore the infrastructure can't nicely display the failures.

1b23079936 [wasm] Int64Lowering of Int64Add on ia32 and arm. 
Int64Add is lowered to a new turbofan operator, Int32AddPair. The new
operator takes 4 inputs an generates 2 outputs. The inputs are the low
word of the left input, high word of the left input, the low word of the
right input, and high word of the right input. The ouputs are the low
and high word of the result of the addition.

ddc626e1cf [wasm] Int64Lowering of I64Shl on ia32. 
I64Shl is lowered to a new turbofan operator, WasmWord64Shl. The new
operator takes 3 inputs, the low-word input, the high-word input, and
the shift, and produces 2 output, the low-word output and the high-word
output.

At the moment I implemented the lowering only for ia32, but I think the
CL is already big enough. I will add the other platforms in separate
CLs.

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.

otherwise the CL would be even bigger, but this can easily and

5768fcf12c Fix the CPU feature detection. 
Move all of the CPU detection logic to the CPU class, and make
all other code use the CPU class for feature detection.

This also fixes the ARM CPU feature detection logic, which was
based on fragile string search in /proc/cpuinfo. Now we use
ELF hwcaps if available, falling back to sane(!!) parsing of
/proc/cpuinfo for CPU features.

The ia32 and x64 code was also cleaned up to make it usable
outside the assembler.

53310ac152 Added a version of the v8::HandleScope constructor with an Isolate and use that consistently. 
I tried to limit the use of v8::Isolate::GetCurrent() and v8::internal::Isolate::Current() as much as possible, but sometimes this would have involved restructuring tests quite a bit, which is better left for a separate CL.

e4edbb0535 Cleaned up CpuFeature scope handling. 
First of all, it has nothing to do with Isolates, it is related to the assembler
at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up
some platform-specific stuff on the way.

Note that there are some things which still need some cleanup, like e.g. using
EnumSet instead of uint64_t, making Probe() more uniform across platforms etc.,
but the CL is already big enough.

fb6776e84a Made Isolate a mandatory parameter for everything Handle-related. 
Unified parameter order of CreateHandle with the rest of v8 on the way. A few
Isolate::Current()s had to be introduced, which is not nice, and not every place
will win a beauty contest, but we can clean this up later easily in smaller steps.

Make the isolate accessible via the assembler.

Only for ia32 at this point. If this looks OK to you I will port it.
