Fortran allows a generic procedure interface to have the same name as a derived type in the same scope or the same name as one of its specific procedures. (It can't have both since a derived type and specific procedure can't have the same name in a scope.) Some popular compilers allow generic interfaces with distinct accessible homonymous specific procedures to be merged by USE association. Thsi compiler does not, and for good reason: it leads to ambiguity in cases where a procedure name appears outside a reference, such as in a PROCEDURE declaration statement as the procedure's interface, the target of a procedure pointer assignment statement, or as an actual argument. This patch cleans up the code that handles these cases, improves some error messages, and adds more tests. Resolves https://github.com/llvm/llvm-project/issues/60228.

The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
