IMPALA-4550: Fix CastExpr analysis for substituted slots

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 set the noOp_ flag to the correct value in all cases.
