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.
