5570 (output_vec_const_move): Add support for XXSPLTIB. If we are
5571 loading up 0/-1 into Altivec registers, prefer using VSPLTISW
5572 instead of XXLXOR/XXLORC.
5573 (rs6000_expand_vector_init): Add support for ISA 3.0 word splat

5589 (vsx_mov<mode>): Replace single move that handled all vector types
5590 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
5591 moves (when -mvsx-timode is in effect) into the main vector
5592 moves. Eliminate separate moves for <VSr> <VSa>, where the
5593 preferred register class (<VSr>) is listed first, and the
5594 secondary register class (<VSa>) is listed second with a '?' to
5595 discourage use. Prefer loading 0/-1 in any VSX register for ISA
5596 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
5597 that if the register was involved in a slow operation, the
5598 clear/set operation does not wait for the slow operation to
5599 finish. Adjust the length attributes for 32-bit mode. Use
5600 rs6000_output_move_128bit and drop the use of the string
5601 instructions for 32-bit movti when -mvsx-timode is in effect. Use
5602 spacing so that the alternatives and attributes don't generate
5603 long lines, and put things in columns, so that it is easier to
5604 match up the operands and attributes with the insn alternatives.
