Off the cuff I'd think that IR containing MF seems most reasonable and
the use of metadata to contain it seems to be good from two
perspectives I think:

a) it already exists,
b) oddly enough that we could get rid of the metadata and still have a
valid module/compilation unit seems like it might be interestingly
useful, but I'm not sure what uses there are off the top of my head.

That said, I really have no preference either way, just idle
speculation. Probably similar to you since we've both not thought
deeply upon it :)

The MDString stuff does seem like it might be useful in general if
we'd like to have that though.
