> While working on SYSTEMML-1554, an additional bug was uncovered. Specifically, with the IPA scalar replacement enhancement, the {{org.apache.sysml.test.integration.functions.misc.DataTypeChangeTest#testDataTypeChangeValidate4c}} test has started to fail.  Looking into it, it fails due to trying to cast a Matrix to a Scalar object.  At a deeper level, it looks like the propagated variable map is holding onto the "matrix" `X`, rather than dropping it as it should, since X is turned into a scalar by the call `X = foo(X)`.  Interestingly, the FunctionOp for the `foo` function is marked as having an `Unknown` datatype and valuetype.  Overall, this seems like a bug that was just hidden before, rather than being newly introduced.
