14295 (vsx_mov<mode>): Replace single move that handled all vector types
14296 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
14297 moves (when -mvsx-timode is in effect) into the main vector
14298 moves. Eliminate separate moves for <VSr> <VSa>, where the
14299 preferred register class (<VSr>) is listed first, and the
14300 secondary register class (<VSa>) is listed second with a '?' to
14301 discourage use. Prefer loading 0/-1 in any VSX register for ISA
14302 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
14303 that if the register was involved in a slow operation, the
14304 clear/set operation does not wait for the slow operation to
14305 finish. Adjust the length attributes for 32-bit mode. Use
14306 rs6000_output_move_128bit and drop the use of the string
14307 instructions for 32-bit movti when -mvsx-timode is in effect. Use
14308 spacing so that the alternatives and attributes don't generate
14309 long lines, and put things in columns, so that it is easier to
14310 match up the operands and attributes with the insn alternatives.
