	* ipa-reference.c (mark_load): Use get_base_address.
	(mark_store): Likewise.

	* tree-ssa-ccp.c (maybe_fold_reference): Avoid introducing
	not useless type conversions.
	* ipa-pure-const.c (check_op): Handle MEM_REF.
	* cfgexpand.c (expand_debug_expr): Fold MEM_REFs in debug
	expressions to avoid handing non-canonicalized MEM_EXPRs
	to the alias-oracle from the scheduler.
