  Log Message:
  [DAG] SelectionDAG::GetDemandedBits - don't simplify opaque constants

I'm actually trying to get rid of GetDemandedBits - but while dismantling it I noticed that we were altering opaque constants. Fixing that causes a FP_TO_INT_SAT regression that should be addressed separately - I'll raise a bug.
