PPC/s390: [ptr-compr][turbofan] Make compressions no-ops

Browse Source 
Port 1821aff2d0

Original Commit Message:

    Since we can just use the lower bits, we can make the compressions no-ops.
    As a note, they still change the representation so that the machine graph
    verifier is happy.

    X64's version of: https://chromium-review.googlesource.com/c/v8/v8/+/1751722
