1931 (output_vec_const_move): Add support for XXSPLTIB. If we are

1951 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
1952 moves (when -mvsx-timode is in effect) into the main vector
1953 moves. Eliminate separate moves for <VSr> <VSa>, where the
1954 preferred register class (<VSr>) is listed first, and the
1955 secondary register class (<VSa>) is listed second with a '?' to
1956 discourage use. Prefer loading 0/-1 in any VSX register for ISA
1957 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
1958 that if the register was involved in a slow operation, the
1959 clear/set operation does not wait for the slow operation to
1960 finish. Adjust the length attributes for 32-bit mode. Use
1961 rs6000_output_move_128bit and drop the use of the string
1962 instructions for 32-bit movti when -mvsx-timode is in effect. Use
1963 spacing so that the alternatives and attributes don't generate
1964 long lines, and put things in columns, so that it is easier to
1965 match up the operands and attributes with the insn alternatives.
