cea227af0c modify ascent to avoid Option when possible 
Whereas before all data on the parser stack was always stored in an
`&mut Option<T>` slot, we know analyze whether the option is truly
needed. The idea is roughly this: for each state, we analyze its actions
to see what suffix of its stack it will *definitely* pop and which
suffix it *may* pop. This is basically the difference between the
largest and shortest prefixes.
