  [clang][codegen] Add a verifier IR pass before any further passes. (#68015)

This helps check clang generated good IR in the first place, as
otherwise this can cause UB in subsequent passes, with the final
verification pass not catching any issues.

This for example would have helped catch
https://github.com/llvm/llvm-project/issues/67937 earlier.
