7292 moves. Eliminate separate moves for <VSr> <VSa>, where the
7293 preferred register class (<VSr>) is listed first, and the
7294 secondary register class (<VSa>) is listed second with a '?' to
7295 discourage use. Prefer loading 0/-1 in any VSX register for ISA
7296 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
7297 that if the register was involved in a slow operation, the
7298 clear/set operation does not wait for the slow operation to
7299 finish. Adjust the length attributes for 32-bit mode. Use
7300 rs6000_output_move_128bit and drop the use of the string
7301 instructions for 32-bit movti when -mvsx-timode is in effect. Use
7302 spacing so that the alternatives and attributes don't generate
7303 long lines, and put things in columns, so that it is easier to
7304 match up the operands and attributes with the insn alternatives.
