3822 moves. Eliminate separate moves for <VSr> <VSa>, where the
3823 preferred register class (<VSr>) is listed first, and the
3824 secondary register class (<VSa>) is listed second with a '?' to
3825 discourage use. Prefer loading 0/-1 in any VSX register for ISA
3826 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
3827 that if the register was involved in a slow operation, the
3828 clear/set operation does not wait for the slow operation to
3829 finish. Adjust the length attributes for 32-bit mode. Use
3830 rs6000_output_move_128bit and drop the use of the string
3831 instructions for 32-bit movti when -mvsx-timode is in effect. Use
3832 spacing so that the alternatives and attributes don't generate
3833 long lines, and put things in columns, so that it is easier to
3834 match up the operands and attributes with the insn alternatives.
