      Reland "[liftoff][arm64] Zero-extend offsets also for SIMD" · 5e90a612
      Clemens Backes authored 
      This is a reland of b99fe75c.
The test is now skipped on non-SIMD hardware.

Original change's description:
> [liftoff][arm64] Zero-extend offsets also for SIMD
>
> This extends https://crrev.com/c/2917612 also for SIMD, which
> (sometimes) uses the special {GetMemOpWithImmOffsetZero} method.
> As part of this CL, that method is renamed to {GetEffectiveAddress}
> which IMO is a better name. Also, it just returns a register to make the
> semantic of that function obvious in the signature.
>
> Drive-by: When sign extending to 32 bit, only write to the W portion of
>           the register. This is a bit cleaner, and I first thought that
>           this would be the bug.
