This change replaces the 5 remaining calls to Bind (generational
lifetime) with GetHandle (reference counting). The handles
are now stored in persistent.Maps, which simplifies the
invalidation logic.
All 5 have span.URIs as keys:
symbolizeHandles
parse{Mod,Work}Handles
mod{Tidy,Why}Handles
Also, factor the functions that use these maps to have a common form:
- a fooImpl function that returns an R result and an error;
- a foo wrapper that decorates it with caching.
- a local fooResult type, defined struct{R; error} that is the cache entry.
The functions for getting/setting map entries are all inlined.
The fooHandle types are all replaced by *memoize.Handle, now that
their use is local.
No behavior change is intended.
The other uses of Bind are deleted in these CLs:

We can use a property that split does a dfs search for the key before
doing an actual work. This allows us to do a low-cost early return if
there is no key to delete.

Use treap (https://en.wikipedia.org/wiki/Treap) as a persistent map to avoid copying s.goFiles across generations.
Maintain an additional s.parseKeysByURIMap to avoid scanning s.goFiles on individual file's content invalidation.
This on average reduces didChange latency on internal codebase from 160ms to 150ms.
In a followup the same approach can be used to avoid copying s.files, s.packages, and s.knownSubdirs.
