  DAG: Fold bitcast of scalar_to_vector to anyext

scalar_to_vector is difficult to make appear and test,
but I found one case where this makes an observable difference.
It fires more often than this in the test suite, but most of them
have no net result in the final code. This helps reduce regressions
in a future commit.
