7282 moves. Eliminate separate moves for <VSr> <VSa>, where the
7283 preferred register class (<VSr>) is listed first, and the
7284 secondary register class (<VSa>) is listed second with a '?' to
7285 discourage use. Prefer loading 0/-1 in any VSX register for ISA
7286 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
7287 that if the register was involved in a slow operation, the
7288 clear/set operation does not wait for the slow operation to
7289 finish. Adjust the length attributes for 32-bit mode. Use
7290 rs6000_output_move_128bit and drop the use of the string
7291 instructions for 32-bit movti when -mvsx-timode is in effect. Use
7292 spacing so that the alternatives and attributes don't generate
7293 long lines, and put things in columns, so that it is easier to
7294 match up the operands and attributes with the insn alternatives.
