12744 [SSA_NAME]: Print the name's def stmt on its own line. When printing
12745 the node's def stmt, avoid printing an unwanted trailing newline by
12746 replacing the call to print_gimple_stmt() with its inlined body and
12747 adjusting it to not set pp_needs_newline and to call pp_flush()
12748 instead of pp_newline_and_flush().

21781 (vsx_mov<mode>): Replace single move that handled all vector types
21782 with separate 32-bit and 64-bit moves. Combine the movti_<bit>
21783 moves (when -mvsx-timode is in effect) into the main vector
21784 moves. Eliminate separate moves for <VSr> <VSa>, where the
21785 preferred register class (<VSr>) is listed first, and the
21786 secondary register class (<VSa>) is listed second with a '?' to
21787 discourage use. Prefer loading 0/-1 in any VSX register for ISA
21788 3.0, and Altivec registers for ISA 2.06/2.07 (PR target/70915) so
21789 that if the register was involved in a slow operation, the
21790 clear/set operation does not wait for the slow operation to
21791 finish. Adjust the length attributes for 32-bit mode. Use
21792 rs6000_output_move_128bit and drop the use of the string
21793 instructions for 32-bit movti when -mvsx-timode is in effect. Use
21794 spacing so that the alternatives and attributes don't generate
21795 long lines, and put things in columns, so that it is easier to
21796 match up the operands and attributes with the insn alternatives.
