    aarch64: Fix up casesi patterns for purecap
    
    We were using DImode for these scratch registers which led to assembly
    failures for jump tables on Purecap Morello.
    
    gcc/ChangeLog:
    
            * config/aarch64/aarch64.md (@casesi_dispatch<mode>): Use ADDR
            for scratch registers used to hold pointers.
            (*casesi_dispatch): Likewise.
