    Re: PowerPC: implement md_operand to parse register names
    
    I meant to make this change before committing, to let compilers know
    the code on the false branch of md_parse_name is dead.
    
            * config/tc-ppc.c (ppc_parse_name): Return void.
            * config/tc-ppc.h (md_parse_name): Always true.
            (ppc_parse_name): Update prototype.
