23083 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
23084 moves (when -mvsx-timode is in effect) into the main vector
23085 moves. Eliminate separate moves for <VSr> <VSa>, where the
23086 preferred register class (<VSr>) is listed first, and the
23087 secondary register class (<VSa>) is listed second with a '?' to
23088 discourage use. Prefer loading 0/-1 in any VSX register for ISA
23089 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
23090 that if the register was involved in a slow operation, the
23091 clear/set operation does not wait for the slow operation to
23092 finish. Adjust the length attributes for 32-bit mode. Use
23093 rs6000_output_move_128bit and drop the use of the string
23094 instructions for 32-bit movti when -mvsx-timode is in effect. Use
23095 spacing so that the alternatives and attributes don't generate
23096 long lines, and put things in columns, so that it is easier to
23097 match up the operands and attributes with the insn alternatives.
