	* cfgexpand.c (expand_used_vars): Allocate space for partitions based
	on PARM_DECLs or RESULT_DECLs only if they are ignored for debug info

	* tree-ssa-coalesce.c (coalesce_ssa_name): If optimization is disabled,
	require that all the names based on a PARM_DECL or a RESULT_DECL that
	isn't ignored for debug info be coalesced.
