      [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.

      [wasm][liftoff] Delete unused parameter in StoreTaggedPointer · 8e7d2844
      Andreas Haas authored 
      The {offset_reg} parameter was introduced so that the signature of
StoreTaggedPointer is the same as for Store, and also to prepare for
potential later uses. However, handling the parameter would introduce
additional complexity, and chances are low that it will ever be used.
That's why this CL just removes it.
