5556 moves. Eliminate separate moves for <VSr> <VSa>, where the
5557 preferred register class (<VSr>) is listed first, and the
5558 secondary register class (<VSa>) is listed second with a '?' to
5559 discourage use. Prefer loading 0/-1 in any VSX register for ISA
5560 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
5561 that if the register was involved in a slow operation, the
5562 clear/set operation does not wait for the slow operation to
5563 finish. Adjust the length attributes for 32-bit mode. Use
5564 rs6000_output_move_128bit and drop the use of the string
5565 instructions for 32-bit movti when -mvsx-timode is in effect. Use
5566 spacing so that the alternatives and attributes don't generate
5567 long lines, and put things in columns, so that it is easier to
5568 match up the operands and attributes with the insn alternatives.
