A fairly recent introduction of runtime I/O APIs called OutputDerivedType() and InputDerivedType() didn't cover NAMELIST I/O's need to access non-type-bound generic interfaces for user-defined derived type I/O when those generic interfaces are defined in some scope other than the one that defines the derived type. The patch adds a new data structure shared between lowering and the runtime that can represent all of the cases that can arise with non-type-bound defined I/O. It can represent scopes in which non-type-bound defined I/O generic interfaces are inaccessible, too, due to IMPORT statements. The data structure is now an operand to OutputDerivedType() and InputDerivedType() as well as a data member in the NamelistGroup structure. Differential Revision: https://reviews.llvm.org/D148257
