During slot substitution, the type of the child of a CastExpr can
change. If the previous child type matched the CastExpr, then the cast
was flagged as noOp_. During substitution and subsequent re-analysis
the noOp_ flag was not revisited so that no cast was performed, even
after it had become necessary.
The fix is to always set noOp_ to the correct value in
CastExpr.analyze().
