This reverts commit 9b1e174f.

Reason for revert: Breaks arm64 sim debug build - https://ci.chromium.org/p/v8/builders/ci/V8%20Linux%20-%20arm64%20-%20sim%20-%20debug/17609

Original change's description:
> [ptr-compr] Storing a Tagged value stores the lower 32 bits
> 
> This CL changes the Tagged stores when pointer compression is enabled.
> It shouldn't affect anything for the time being since if we have pointer
> compression enabled, we are going to be storing Compressed values. Later,
> we will eliminate the Compressed representation and that it's where it
> will come into effect.
> 
> The Arm64 side of the CL looks bigger since we eliminated the opcode in
> https://chromium-review.googlesource.com/c/v8/v8/+/1803345.
