10905 moves. Eliminate separate moves for <VSr> <VSa>, where the
10906 preferred register class (<VSr>) is listed first, and the
10907 secondary register class (<VSa>) is listed second with a '?' to
10908 discourage use. Prefer loading 0/-1 in any VSX register for ISA
10909 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
10910 that if the register was involved in a slow operation, the
10911 clear/set operation does not wait for the slow operation to
10912 finish. Adjust the length attributes for 32-bit mode. Use
10913 rs6000_output_move_128bit and drop the use of the string
10914 instructions for 32-bit movti when -mvsx-timode is in effect. Use
10915 spacing so that the alternatives and attributes don't generate
10916 long lines, and put things in columns, so that it is easier to
10917 match up the operands and attributes with the insn alternatives.
