14329 (vsx_mov<mode>): Replace single move that handled all vector types
14330 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
14331 moves (when -mvsx-timode is in effect) into the main vector
14332 moves. Eliminate separate moves for <VSr> <VSa>, where the
14333 preferred register class (<VSr>) is listed first, and the
14334 secondary register class (<VSa>) is listed second with a '?' to
14335 discourage use. Prefer loading 0/-1 in any VSX register for ISA
14336 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
14337 that if the register was involved in a slow operation, the
14338 clear/set operation does not wait for the slow operation to
14339 finish. Adjust the length attributes for 32-bit mode. Use
14340 rs6000_output_move_128bit and drop the use of the string
14341 instructions for 32-bit movti when -mvsx-timode is in effect. Use
14342 spacing so that the alternatives and attributes don't generate
14343 long lines, and put things in columns, so that it is easier to
14344 match up the operands and attributes with the insn alternatives.
