This reverts commit 1786f8d7.

Reason for revert: https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64/44442/overview

Original change's description:
> [arm64][liftoff] Fix trap handling on load lane
>
> This fixes the registered {protected_load_pc} to (always) point to the
> actual load instruction. If {dst != src} we would emit a register move
> before the load, and the trap handler would then not recognize the PC
> where the signal occurs, leading to a segfault.
