    rs6000: Fix infinite loop building ghostscript and icu [PR93658]

    Fix rs6000_legitimate_address_p(), which erroneously marks a valid Altivec
    address as being invalid, which causes LRA's process_address()  to go into
    an infinite loop spilling the same address over and over again.
    Include Mike's earlier commits that fix bugs this patch exposes.
