I just did this myself (r123234). Instead of rolling your own updating
code, just substitute

  return SimplifyTerminatorOnSelect(SI, Select->getCondition(),
TrueBB, FalseBB);

for it and it should Just Work.
This replaces everything in your last patch after the declaration of
FalseBB to the end of the if block.
