A defined assignment generic interface for a given LHS/RHS type & rank combination may have a specific procedure with LHS dummy argument that is neither allocatable nor pointer, or specific procedure(s) whose LHS dummy arguments are allocatable or pointer. It is possible to have two specific procedures if one's LHS dummy argument is allocatable and the other's is pointer. However, the runtime doesn't work with LHS dummy arguments that are allocatable, and will crash with a mysterious "invalid descriptor" error message. Extend the list of special bindings to include ScalarAllocatableAssignment and ScalarPointerAssignment, use them when appropriate in the runtime type information tables, and handle them in Assign() in the runtime support library.
