22247 (vsx_mov<mode>): Replace single move that handled all vector types
22248 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
22249 moves (when -mvsx-timode is in effect) into the main vector
22250 moves. Eliminate separate moves for <VSr> <VSa>, where the
22251 preferred register class (<VSr>) is listed first, and the
22252 secondary register class (<VSa>) is listed second with a '?' to
22253 discourage use. Prefer loading 0/-1 in any VSX register for ISA
22254 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
22255 that if the register was involved in a slow operation, the
22256 clear/set operation does not wait for the slow operation to
22257 finish. Adjust the length attributes for 32-bit mode. Use
22258 rs6000_output_move_128bit and drop the use of the string
22259 instructions for 32-bit movti when -mvsx-timode is in effect. Use
22260 spacing so that the alternatives and attributes don't generate
22261 long lines, and put things in columns, so that it is easier to
22262 match up the operands and attributes with the insn alternatives.
