Do not gate the coroutine extension points on the LLVM passes. Without running this pass, the generated IR cannot be used by the LLVM tooling. This allows generating the LLVM IR to debug issues in the LLVM backend. I encountered this when trying to isolate a debug info generation bug which seems to be caused by the SRoA pass in LLVM. By allowing to emit the LLVM IR without the LLVM optimizations, it is possible to isolate the LLVM pass operation via `opt` from LLVM.
