That argument is otherwise completely ignored at runtime, and there is no code generated for it as the library procedure has no kind argument. This confuses the scalarizer which expects to see every argument of elemental functions used when calling a procedure. This change removes the argument from the scalarization lists at the beginning of the scalarization process, so that the argument is completely ignored.
