- The optimization reduces time spent in `LLFirProvider.SymbolProvider`
during my tests by 30-90% in some highlighted files. In other
performance tests, the optimization makes performance worse, so more
work is needed. In general, higher workload tests run faster with the
optimization, while lower workload tests run slower. This is expected
as the optimization trades short-term performance (for building
classifier/callable name sets) in favor of long-term speedup.
- The changes should also reduce the size of declaration caches like
`LLFirProviderHelper.classifierByClassId`.
- Building the name sets has a second use, as a similar optimization can
be implemented for dependent module providers, which may rely on the
sets computed here.
