1632         (vsx_mov<mode>): Replace single move that handled all vector types
1633         with separate 32-bit and 64-bit moves.  Combine the movti_<bit>
1634         moves (when -mvsx-timode is in effect) into the main vector
1635         moves.  Eliminate separate moves for <VSr> <VSa>, where the
1636         preferred register class (<VSr>) is listed first, and the
1637         secondary register class (<VSa>) is listed second with a '?' to
1638         discourage use.  Prefer loading 0/-1 in any VSX register for ISA
1639         3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
1640         that if the register was involved in a slow operation, the
1641         clear/set operation does not wait for the slow operation to
1642         finish.  Adjust the length attributes for 32-bit mode.  Use
1643         rs6000_output_move_128bit and drop the use of the string
1644         instructions for 32-bit movti when -mvsx-timode is in effect.  Use
1645         spacing so that the alternatives and attributes don't generate
1646         long lines, and put things in columns, so that it is easier to
1647         match up the operands and attributes with the insn alternatives.
