I merged a patch yesterday (https://github.com/llvm/llvm-project/pull/128980) that strengthened error detection of indistinguishable specific procedures in a type-bound generic procedure, and broke a couple of tests. Refine the check so that it doesn't flag valid cases of overridden bindings, and add a thorough test with all of the boundary cases that I can think of.
