Do not run `cf-to-llvm` as part of `func-to-llvm`. This commit fixes https://github.com/llvm/llvm-project/issues/70982. This commit changes the way how `func.func` ops are lowered to LLVM. Previously, the signature of the entire region (i.e., entry block and all other blocks in the `func.func` op) was converted as part of the `func.func` lowering pattern. Now, only the entry block is converted. The remaining block signatures are converted together with `cf.br` and `cf.cond_br` as part of `cf-to-llvm`. All unstructured control flow is not converted as part of a single pass (`cf-to-llvm`). `func-to-llvm` no longer deals with unstructured control flow. Also add more test cases for control flow dialect ops. Note: This PR is in preparation of #120431, which adds an additional GPU-specific lowering for `cf.assert`. This was a problem because `cf.assert` used to be converted as part of `func-to-llvm`. Note for LLVM integration: If you see failures, add `-convert-cf-to-llvm` to your pass pipeline.
