 TODO:
-* condition register allocation
 * gpr0 allocation
 * implement do-loop -> bdnz transform
 * implement powerpc-64 for darwin
 * use stfiwx in float->int
+* be able to combine sequences like the following into 2 instructions:
+       lis r2, ha16(l2__ZTV4Cell)
+       la r2, lo16(l2__ZTV4Cell)(r2)
+       addi r2, r2, 8
 * should hint to the branch select pass that it doesn't need to print the
   second unconditional branch, so we don't end up with things like:
        b .LBBl42__2E_expand_function_8_674     ; loopentry.24
        b .LBBl42__2E_expand_function_8_42      ; NewDefault
        b .LBBl42__2E_expand_function_8_42      ; NewDefault
