Suggested by mdempsky in CL 38232. This allows us to use the Frontend field to associate frontend state and information with a function. See the following CL in the series for examples. This is a giant CL, but it is almost entirely routine refactoring. The ssa test API is starting to feel a bit unwieldy. I will clean it up separately, once the dust has settled. Passes toolstash -cmp.
