genattrtab.c (write_insn_cases): New function, split out from write_attr_case. 

* genattrtab.c (write_insn_cases): New function, split out from
	write_attr_case.  Correctly handle define_peepholes when printing
	the instruction name.
	(write_attr_case, write_const_num_delay_slots): Use write_insn_cases.
