Summary: Many of these were already implemented, and I just annotated the tests and/or the code. C752 was a simple check to verify that CONTIGUOUS components are arrays with C754 proved to be virtually identical to C750 that I implemented previously. This caused me to remove the distinction between specification expressions for type parameters and bounds expressions that I'd previously created. the POINTER attribute. I also changed the error messages to specify that errors in specification expressions could arise from either bad derived type components or type parameters. In cases where we detect a type param that was not declared, I created a symbol marked as erroneous. That avoids subsequent semantic process for expressions containing the symbol. This change caused me to adjust tests resolve33.f90 and resolve34.f90. Also, I avoided putting out error messages for erroneous type param symbols in `OkToAddComponent()` in resolve-names.cpp and in `EvaluateParameters()`, type.cpp. C756 checks that procedure components have the POINTER attribute.
