5086 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
5087 moves (when -mvsx-timode is in effect) into the main vector
5088 moves. Eliminate separate moves for <VSr> <VSa>, where the
5089 preferred register class (<VSr>) is listed first, and the
5090 secondary register class (<VSa>) is listed second with a '?' to
5091 discourage use. Prefer loading 0/-1 in any VSX register for ISA
5092 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
5093 that if the register was involved in a slow operation, the
5094 clear/set operation does not wait for the slow operation to
5095 finish. Adjust the length attributes for 32-bit mode. Use
5096 rs6000_output_move_128bit and drop the use of the string
5097 instructions for 32-bit movti when -mvsx-timode is in effect. Use
5098 spacing so that the alternatives and attributes don't generate
5099 long lines, and put things in columns, so that it is easier to
5100 match up the operands and attributes with the insn alternatives.
