12715 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
12716 moves (when -mvsx-timode is in effect) into the main vector
12717 moves. Eliminate separate moves for <VSr> <VSa>, where the
12718 preferred register class (<VSr>) is listed first, and the
12719 secondary register class (<VSa>) is listed second with a '?' to
12720 discourage use. Prefer loading 0/-1 in any VSX register for ISA
12721 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
12722 that if the register was involved in a slow operation, the
12723 clear/set operation does not wait for the slow operation to
12724 finish. Adjust the length attributes for 32-bit mode. Use
12725 rs6000_output_move_128bit and drop the use of the string
12726 instructions for 32-bit movti when -mvsx-timode is in effect. Use
12727 spacing so that the alternatives and attributes don't generate
12728 long lines, and put things in columns, so that it is easier to
12729 match up the operands and attributes with the insn alternatives.
