	* tree-cfg.c (verify_types_in_gimple_reference): Verify
	TARGET_MEM_REF a bit.
	* tree-ssa-address.c (addr_for_mem_ref): Adjust.
	(create_mem_ref_raw): Always create TMR_OFFSET, store the
	alias pointer type via it.
	(copy_mem_ref_info): Adjust.
	(maybe_fold_tmr): Likewise.
	* tree.c (mem_ref_offset): Also handle TARGET_MEM_REF.
	(reference_alias_ptr_type): Likewise.
	* tree.def (TARGET_MEM_REF): Remove TMR_ORIGINAL operand,
	adjust documentation of TMR_OFFSET operand.
	* alias.c (get_alias_set): Do not look at TMR_ORIGINAL but
	use the alias pointer type.
	* expr.c (expand_expr_real_1): Do not use TMR_ORIGINAL to
	initialize mem attrs but the TMR itself.
	* tree-eh.c (tree_could_trap_p): Handle TARGET_MEM_REF
	similar to MEM_REF.
	* tree-pretty-print.c (dump_generic_node): Do not dump TMR_ORIGINAL.
	* tree-ssa-loop-ivopts.c (idx_remove_ssa_names): Remove.
	(unshare_and_remove_ssa_names): Likewise.
	(copy_ref_info): Adjust.
	* tree-ssa-pre.c (create_component_ref_by_pieces_1): Simplify
	TARGET_MEM_REF case.
	* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Do not look
	at TMR_ORIGINAL.
	* tree.h (TMR_ORIGINAL): Remove.
	* gimple.c (get_base_address): For TARGET_MEM_REF with a
	symbol return that.
	* tree-dfa.c (get_ref_base_and_extent): Handle TARGET_MEM_REF
	with a symbol.
	(get_addr_base_and_unit_offset): Likewise.
	* tree-ssa-alias.c (indirect_ref_may_alias_decl_p): Handle
	TARGET_MEM_REFs.
	(indirect_ref_may_alias_decl_p): Likewise.
	(refs_may_alias_p_1): Do not bail out for TARGET_MEM_REFs.
