[DAGCombine] Fold (X & ~Y) | Y with truncated not
This extends the (X & ~Y) | Y to X | Y fold to also work if ~Y is
a truncated not (when taking into account the mask X). This is
done by exporting the infrastructure added in D124856 and reusing
it here.
I've retained the old value of AllowUndefs=false, though probably
this can be switched to true with extra test coverage.
