Adrian Prantl 137597d4f4 Add a verifier check that rejects non-distinct DISubprogram function 
attachments. They would crash the backend, which expects all
DISubprograms that are not part of the type system to have a unit field.

Clang right before https://reviews.llvm.org/D79967 would generate this
kind of broken IR.

Thanks to Fangrui for fixing an assembler test I had missed!
