Sanjay Patel b7d4502f35 [DAG] optimize negation of bool 
Use mask and negate for legalization of i1 source type with SIGN_EXTEND_INREG.
With the mask, this should be no worse than 2 shifts. The mask can be eliminated
in some cases, so that should be better than 2 shifts.

This change exposed some missing folds related to negation:

There may be others, so please let me know if you see any regressions.
