  [mlir] Delay adding the __resume function

The __resume function trips up LLVM's 'X86 DAG->DAG Instruction Selection' unless optimizations are disabled.

Only adding the __resume function when it's needed allows lowering through AsyncToLLVM and LLVM without '-O0' as long as the coroutine functionality is not used.
