5572 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
5573 moves (when -mvsx-timode is in effect) into the main vector
5574 moves. Eliminate separate moves for <VSr> <VSa>, where the
5575 preferred register class (<VSr>) is listed first, and the
5576 secondary register class (<VSa>) is listed second with a '?' to
5577 discourage use. Prefer loading 0/-1 in any VSX register for ISA
5578 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
5579 that if the register was involved in a slow operation, the
5580 clear/set operation does not wait for the slow operation to
5581 finish. Adjust the length attributes for 32-bit mode. Use
5582 rs6000_output_move_128bit and drop the use of the string
5583 instructions for 32-bit movti when -mvsx-timode is in effect. Use
5584 spacing so that the alternatives and attributes don't generate
5585 long lines, and put things in columns, so that it is easier to
5586 match up the operands and attributes with the insn alternatives.
