gcse.c (replace_store_insn): Use delete_insn.

Browse source 
* gcse.c (replace_store_insn): Use delete_insn.
	* loop.c (move_movables): Likewise; avoid delete_insn
	from clobbering notes moved elsewhere.
	(check_dbra_loop): Use delete_insn.
	* ssa.c (convert_from_ssa): Likewise.
	* cse.c (cse_insn): Use delete_insn.
