c50ffcb7fc Reenable this pass, fixing the bugs in it. 
It now correctly deletes unreachable blocks and blocks that are empty.

5956922a2d Be careful when looking through a vbit_convert. Optimizing this: 
(vector_shuffle
  (vbitconvert (vbuildvector (copyfromreg v4f32), 1, v4f32), 4, f32),
  (undef, undef, undef, undef), (0, 0, 0, 0), 4, f32)
to the
  vbitconvert
is a very bad idea.

51dabfb283 When SimplifySetCC was moved to the DAGCombiner, it was never removed from 
SelectionDAG and it has since bitrotted.  Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.

This fixes obscure bugs.
