26ecb4a1d7 [Turbofan] Add ia32 support for 4 and 16 byte moves and swaps.
- Adds move/swap handling for 4 and 16 bytes to ia32.
- Register allocator now only requests 4 bytes for floats on ia32 and arm.
- We probably need similar support in mips.

d9e8764f81 [ic] Split LoadIC into LoadGlobalIC and LoadIC.
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.

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.

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.

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.

ee718489fe Drop unused rdtsc instruction.
We do not use rdtsc anywhere and we won't ever use that in the
future, as it is totally unusable with multicore and out of
order execution.

f8db2414f2 Deprecate FACTORY helper macro.
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.
