* cgen.c (cgen_parse_operand): Renamed from cgen_asm_parse_operand.

	New argument `want'.  Update enum cgen_parse_operand_result values.
	Initialize if CGEN_PARSE_OPERAND_INIT.
	* config/tc-m32r.c (md_begin): Set cgen_parse_operand_fn.
	(md_assemble): Call cgen_asm_init_parse.
	Update call to m32r_cgen_assemble_insn, call as_bad if assembly failed.
