    aarch64: increase alias candidate limit in aarch64-gen
    
    Increase max_num_aliases from 32 to 64 so that aarch64-gen can
    accommodate the additional HINT-space alias added for FEAT_PAuth_LR.
    
    The generated disassembler alias preference list can otherwise exceed
    the old fixed limit.
