18562 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
18563 moves (when -mvsx-timode is in effect) into the main vector
18564 moves. Eliminate separate moves for <VSr> <VSa>, where the
18565 preferred register class (<VSr>) is listed first, and the
18566 secondary register class (<VSa>) is listed second with a '?' to
18567 discourage use. Prefer loading 0/-1 in any VSX register for ISA
18568 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
18569 that if the register was involved in a slow operation, the
18570 clear/set operation does not wait for the slow operation to
18571 finish. Adjust the length attributes for 32-bit mode. Use
18572 rs6000_output_move_128bit and drop the use of the string
18573 instructions for 32-bit movti when -mvsx-timode is in effect. Use
18574 spacing so that the alternatives and attributes don't generate
18575 long lines, and put things in columns, so that it is easier to
18576 match up the operands and attributes with the insn alternatives.
