alias.c (nonoverlapping_memrefs): Use REGNO_PTR_FRAME_P.

	* alias.c (nonoverlapping_memrefs): Use REGNO_PTR_FRAME_P.
	* emit-rtl.c (change_address): Fix typo in default alignment.
	(adjust_address_1): Use mode of NEW, not MODE, when setting size.
	* expr.c (highest_pow2_factor, case WITH_RECORD_EXPR): New case.
	* rtl.h (REGNO_PTR_FRAME_P): New macro.

	* expr.c (store_field): Pass tree instead of max size; callers changed.
	Change handling of alignment.
	Only copy to_rtx if is TARGET.

	(emit_cmp_insn): No longer take ALIGN parm; all callers changed.
	(expand_assignment): Change handling of alignment.
	Only copy to_rtx if was original.
	(get_inner_reference): No longer return alginment; callers changed.
	(expand_expr, case COMPONENT_REF): Change handling of alignment.
	(expand_expr, case ADDR_EXPR): Make copy if not sufficiently aligned.
	(compare_from_rtx): Delete ALIGN parm; all callers changed.
	(do_compare_rtx_and_jump): Likewise.
	* expr.h: Reflect above changes.
	* tree.h: Likewise.
