   1 TODO:
   2 * gpr0 allocation
   3 * implement do-loop -> bdnz transform
   4 * implement powerpc-64 for darwin
   5 * use stfiwx in float->int
   6 * take advantage of the darwin red zone in PPC32RegisterInfo.cpp
   7 * be able to combine sequences like the following into 2 instructions:
   8         lis r2, ha16(l2__ZTV4Cell)
   9         la r2, lo16(l2__ZTV4Cell)(r2)
  10         addi r2, r2, 8
  11
  12 * should hint to the branch select pass that it doesn't need to print the
  13   second unconditional branch, so we don't end up with things like:
  14         b .LBBl42__2E_expand_function_8_674     ; loopentry.24
  15         b .LBBl42__2E_expand_function_8_42      ; NewDefault
  16         b .LBBl42__2E_expand_function_8_42      ; NewDefault
