This series of changes makes generation of the bindings dramatically faster, by fixing a number of issues around re-parsing things, re-doing expensive work, doing O(n) scans when O(1) lookups are possible, etc. It also slightly simplifies some of the code by removing the multiprocessing layer for bindings generation. Despite now being single-threaded, the total time for bindings generation on my 16-core machine drops from 8 minutes to nearly instant. (I am not sure what percent speedup that is, but it's huge!)

It's always set to "bindings"
This simplifies the code flow a good bit, and I hope to make this fast
enough that it doesn't matter.
Just call it processChildren now.
Pass tu through instead of doing an expensive re-parse a bunch.
I want to add more precomputed stuff here, let's introduce a helper
object for it first so we don't add a zillion args to every function.
This doesn't need to be created every time, and the search doesn't need
to be linear every time.
