      Turbofan: Add MachineOperators for SIMD. · 1c94bed6
      bbudge authored 
      Takes the SIMD runtime intrinsics as a starting point for defining TF machine operators. The rationale for omitting functions is:

 - Check functions.
 - 'FromXxxBits' functions. These are essentially casts.
 - UInt constructors. int and uint aren't distinguished in wasm.
 - Uint functions, except where their behavior is bitwise different from the Int function.

Some operators are typeless, i.e. they are the same for multiple related types, e.g. logical ops for int types, load/store for float and int types. Use a 'Simd128' prefix for these operators.

      S390: [turbofan] Run everything after representation selection concurrently. · 5d84567a
      bryleun authored 
          Port d1b3d426

    Original commit message:

        Further refactor the pipeline to even run the first scheduler (part of
        the effect control linearization) concurrently. This temporarily
        disables most of the write barrier elimination, but we will get back to
        that later.

        Drive-by-fix: Remove the dead code from ChangeLowering, and stack
        allocate the Typer in the pipeline. Also migrate the AllocateStub to a
        native code builtin, so that we have the code object + a handle to it
        available all the time.

      Use InternalArrays from certain Intl code · 4f374bbc
      littledan authored 
      The ECMA 402 implementation previously pushed directly to real
Arrays, which risks having observably incorrect behavior in the
presence of monkey patching. This patch uses InternalArrays instead
to avoid that hazard.

      Ignore CpuProfiler::SetIdle call when not profiling. · eda8ea16
      dgozman authored 
      It truned out we can enter nested message loop and call
SetIdle from inside the compilation in some obscure
situations. To not whitelist all the possible StateTag values,
we'd better ignore this call when not profiling as it has
no effect anyway.

This patch also reverts DCHECK change from https://codereview.chromium.org/1922703005/.

      Make Isolate::GetStackSample API support simulator · b027b623
      lpy authored 
      Currently GetStackSample doesn't support simulator, thus sampler is aware of
simulator, but since we are moving it out, it shouldn't have knowledge of
simulator. This patch moves the logic using simulator accessible
to Isolate::GetStackSample, so that it supports simulator.
