3852 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
3853 moves (when -mvsx-timode is in effect) into the main vector
3854 moves. Eliminate separate moves for <VSr> <VSa>, where the
3855 preferred register class (<VSr>) is listed first, and the
3856 secondary register class (<VSa>) is listed second with a '?' to
3857 discourage use. Prefer loading 0/-1 in any VSX register for ISA
3858 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
3859 that if the register was involved in a slow operation, the
3860 clear/set operation does not wait for the slow operation to
3861 finish. Adjust the length attributes for 32-bit mode. Use
3862 rs6000_output_move_128bit and drop the use of the string
3863 instructions for 32-bit movti when -mvsx-timode is in effect. Use
3864 spacing so that the alternatives and attributes don't generate
3865 long lines, and put things in columns, so that it is easier to
3866 match up the operands and attributes with the insn alternatives.
