No description provided.

The strategy is the same as in IonBuilder: create an OSR entry block and a second
block merging the two predecessor blocks before the loop.

This is a lot simpler than IonBuilder because we don't attempt to type-specialize
OSR values. If this becomes an issue we'll need a strategy for that. Hopefully
this will be good enough for now until we make bigger changes to how OSR and the
Ion backend work.
