	instruction and possibly with a sign extension.
	(output_vec_const_move): Add support for XXSPLTIB. If we are
	loading up 0/-1 into Altivec registers, prefer using VSPLTISW
	instead of XXLXOR/XXLORC.

	moves.  Eliminate separate moves for <VSr> <VSa>, where the
	preferred register class (<VSr>) is listed first, and the
	secondary register class (<VSa>) is listed second with a '?' to
	discourage use.  Prefer loading 0/-1 in any VSX register for ISA
	3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
	that if the register was involved in a slow operation, the
	clear/set operation does not wait for the slow operation to
	finish.  Adjust the length attributes for 32-bit mode.  Use
	rs6000_output_move_128bit and drop the use of the string
	instructions for 32-bit movti when -mvsx-timode is in effect.  Use
	spacing so that the alternatives and attributes don't generate
	long lines, and put things in columns, so that it is easier to
	match up the operands and attributes with the insn alternatives.
