	PR rtl-optimization/63637
	PR rtl-optimization/60663
	* cse.c (merge_equiv_classes): Set new_elt->cost to MAX_COST
	if elt->cost is MAX_COST for ASM_OPERANDS.
	(find_sets_in_insn): Fix up comment typo.
	(cse_insn): Don't set src_volatile for all non-volatile
	ASM_OPERANDS in PARALLELs, but just those with multiple outputs
	or with "memory" clobber.  Set elt->cost to MAX_COST
	for ASM_OPERANDS in PARALLEL.  Set src_elt->cost to MAX_COST
	if new_src is ASM_OPERANDS and elt->cost is MAX_COST.
