21798 moves. Eliminate separate moves for <VSr> <VSa>, where the
21799 preferred register class (<VSr>) is listed first, and the
21800 secondary register class (<VSa>) is listed second with a '?' to
21801 discourage use. Prefer loading 0/-1 in any VSX register for ISA
21802 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
21803 that if the register was involved in a slow operation, the
21804 clear/set operation does not wait for the slow operation to
21805 finish. Adjust the length attributes for 32-bit mode. Use
21806 rs6000_output_move_128bit and drop the use of the string
21807 instructions for 32-bit movti when -mvsx-timode is in effect. Use
21808 spacing so that the alternatives and attributes don't generate
21809 long lines, and put things in columns, so that it is easier to
21810 match up the operands and attributes with the insn alternatives.
