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
