2019-07-29  Michael Meissner  <meissner@linux.ibm.com>

	* config/rs6000/rs6000.c (rs6000_setup_reg_addr_masks): Enable
	prefixed addressing for any mode that supports offset addressing
	in its default mode.
	* config/rs6000/rs6000.md (mov<mode>_64bit_dm): Split <zero_fp>
	and load to GPR register alternatives.  Document the
	alternatives.  Add support for setting the prefixed and
	non-prefixed instruction length.
	(movtd_64bit_nodm): Set the non-prefixed and prefixed instruction
	lengths.
	(mov<mode>_ppc64): Set the non-prefixed and prefixed instruction
	lengths.
	* config/rs6000/vsx.md (vsx_mov<mode>_64bit): Set the prefixed and
	non-prefixed instruction lengths.
	(vsx_extract_<P:mode>_<VSX_D:mode>_load): Set the prefixed
	attribute.  Set the non-prefixed and prefixed instruction
	lengths.
	(vsx_extract_v4sf_<mode>_load): Set the non-prefixed and prefixed
	instruction lengths.
