- Add the appropriate cpuid checks to detect AVX2 in base/cpu - Add FLAG_enable_avx2 AVX2 depends on AVX support, + a cpuid check with eax=7. This is similar to chromium/src/base/cpu.cc check for AVX2.

AVX has 3-operands shuffle/unpack operations. We currently always require that dst == src0 in all cases, which is not required if we have AVX. For the arch shuffles that map to a single native instruction, add support to check for AVX in the instruction-selector, to not require same as first, and in the code-gen to support generating AVX. The other arch shuffles are slightly more complicated, and can be optimized in a future change.

An improvement to generic shuffle improvement (https://crrev.com/c/2152853) required a temporary SIMD register to hold the mask, rather than pushing it onto a stack. The temporary register requires that we UseUniqueRegister on the inputs, to prevent aliasing, as we will write to the temp. However, we only need this for the generic shuffle. We accidentally over-constraint all other pattern matched shuffles, since they don't use any temps. On a ~2000 line function containing ~150 shuffles (not all of which are generic shuffles), we get 16 less instruction in the native code, and actually see a very small improvement in the overall benchmarks.

We can have more optimizations for this instruction, they leave some junk in the top lanes of dst, but that doesn't matter: - when lane is 1: we use movshdup, this is 4 bytes long - when lane is 2: use movhlps, this is 3 bytes long - otherwise use shufps (4 bytes) or pshufd (5 bytes) All of which are better than insertps (6 bytes).

This CL adds a MachineRepresentation argument to LoopExitValue nodes, as well as a helper to extract it. Since the MachineRepresentation is not used by JS compilation, nodes generated during JS compilation are passed kTagged as a default value.

There is a race in the way we handle deopts that made this test flaky. The race is not hugely important to fix, and is difficult without breaking something else. The best thing to do here is update the test to reflect reality so we can get the test coverage back. This updates the test so that the deopt reason can be found either on the first or second level function. The test assumed it would always be available on the second level function in the profile, but if we get a regular profile tick at the exact wrong time, we could end up with the deopt info getting attached to the first level function. So we accept either.

f64x2.extract_lane can only extract lane 0 or 1. Fix the DCHECK to check for the appropriate lane values.

Registers are spilled differently on arm and intel platforms. Additionally, on arm64 registers are spilled with padding. Therefore the code for safepoint information for spilled registers is platform- dependent now. Additionally the alignment of the frame size is done before the out-of-line code now, so that the safepoint indices can be calculated correctly for spilled registers in out-of-line code. Finally, some code was unimplemented on ia32 and arm, which I added now.

CallRecordWriteStub is used in a background compile thread for JS-to-Wasm wrapper compilation, so it should avoid accessing the isolate. Call the builtin using CallBuiltin which does not require a Handle<Code> object and instead gets the call target directly from the embedded data.

Neither Liftoff nor the WasmGraphBuildingInterface use the parameter, hence drop it.

We were storing the pointer to the WasmModule both as a shared_ptr and as a raw pointer. Maybe this had historical reasons, but now it's just redundant.
