21802 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
21803 moves (when -mvsx-timode is in effect) into the main vector
21804 moves. Eliminate separate moves for <VSr> <VSa>, where the
21805 preferred register class (<VSr>) is listed first, and the
21806 secondary register class (<VSa>) is listed second with a '?' to
21807 discourage use. Prefer loading 0/-1 in any VSX register for ISA
21808 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
21809 that if the register was involved in a slow operation, the
21810 clear/set operation does not wait for the slow operation to
21811 finish. Adjust the length attributes for 32-bit mode. Use
21812 rs6000_output_move_128bit and drop the use of the string
21813 instructions for 32-bit movti when -mvsx-timode is in effect. Use
21814 spacing so that the alternatives and attributes don't generate
21815 long lines, and put things in columns, so that it is easier to
21816 match up the operands and attributes with the insn alternatives.
