12720 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
12721 moves (when -mvsx-timode is in effect) into the main vector
12722 moves. Eliminate separate moves for <VSr> <VSa>, where the
12723 preferred register class (<VSr>) is listed first, and the
12724 secondary register class (<VSa>) is listed second with a '?' to
12725 discourage use. Prefer loading 0/-1 in any VSX register for ISA
12726 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
12727 that if the register was involved in a slow operation, the
12728 clear/set operation does not wait for the slow operation to
12729 finish. Adjust the length attributes for 32-bit mode. Use
12730 rs6000_output_move_128bit and drop the use of the string
12731 instructions for 32-bit movti when -mvsx-timode is in effect. Use
12732 spacing so that the alternatives and attributes don't generate
12733 long lines, and put things in columns, so that it is easier to
12734 match up the operands and attributes with the insn alternatives.
