      [wasm-simd][liftoff][ia32][x64] Implement floating-point roundings · 7f654693
      Ng Zhi An authored 
      Implement f32x4 and f64x2 nearest, trunc, ceil, and floor for ia32 and
x64. arm and arm64 will follow in a future patch, now they just bail out
into a runtime call.

      Bill Budge authored 
      This reverts commit 2000aea5.

Reason for revert: Breaks NumFuzz.

Original change's description:
> Reland^4 "[flags] warn about contradictory flags"
> 
> This is a reland of 0ba115e6
> Changes compared to last reland:
> - Fix Python code trying to write to expected_outcomes, which is now a
>   computed property.
> - Fix remaining place in d8.cc that ignored the --fuzzing flag.
> - Expect flag contradictions for --cache in code_serializer variant.

> Original change's description:

> > Changes:
> > - Also allow second parameter influenced by --cache to be reassigned.
> > - Fix --stress-opt to only --always-opt in the last iteration as before.
