2017-06-23  Aaron Sawdey  <acsawdey@linux.vnet.ibm.com>

	* config/rs6000/rs6000-string.c: (expand_block_clear,
	do_load_for_compare, select_block_compare_mode,
	compute_current_alignment, expand_block_compare,
	expand_strncmp_align_check, expand_strn_compare,
	expand_block_move, rs6000_output_load_multiple)
	Move functions related to string/block move/compare
	to a separate file.
	* config/rs6000/rs6000.c: Move above functions to rs6000-string.c.
	* config/rs6000/rs6000-protos.h (rs6000_emit_dot_insn): Add prototype
	for this function which is now used in two files.
	* config/rs6000/t-rs6000: Add rule to compile rs6000-string.o.
	* config.gcc: Add rs6000-string.o to extra_objs for
	targets powerpc*-*-* and rs6000*-*-*.
