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.
