3825 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
3826 moves (when -mvsx-timode is in effect) into the main vector
3827 moves. Eliminate separate moves for <VSr> <VSa>, where the
3828 preferred register class (<VSr>) is listed first, and the
3829 secondary register class (<VSa>) is listed second with a '?' to
3830 discourage use. Prefer loading 0/-1 in any VSX register for ISA
3831 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
3832 that if the register was involved in a slow operation, the
3833 clear/set operation does not wait for the slow operation to
3834 finish. Adjust the length attributes for 32-bit mode. Use
3835 rs6000_output_move_128bit and drop the use of the string
3836 instructions for 32-bit movti when -mvsx-timode is in effect. Use
3837 spacing so that the alternatives and attributes don't generate
3838 long lines, and put things in columns, so that it is easier to
3839 match up the operands and attributes with the insn alternatives.
