    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.

    gcc/
     PR target/93658
     * config/rs6000/rs6000.c (rs6000_legitimate_address_p): Handle VSX
