I had not considered an MMO flag in the lowering. I'll look that up. Metadata
in LLVM IR could have worked, but like @krzysz00 said, it can be dropped.
Having this "!async" metadata will not cause an incorrect program. But I
believe this current feature is an important change in semantics and not just
an optimization, and hence deserves to be more than just metadata.
