emit-rtl.c (set_mem_attributes_minus_bitpos): Set MEM_POINTER flag.

	* emit-rtl.c (set_mem_attributes_minus_bitpos): Set MEM_POINTER
	flag.
	* explow.c (force_not_mem): Set REG_POINTER flag according to
	MEM_POINTER one.
	* rtl.h (MEM_POINTER): New macro.
	(struct rtx_def): Use integrated for MEM_SCALAR_P and frame_related
	for MEM_POINTER.
