> This PR refactors SwitchBootstraps so that extra EnumDescs and classes are > only passed into bootstraps when needed. Benchmarking shows that in many > cases these are not needed, and avoiding passing them (via binding in the > lists via `MethodHandle::insertArguments`) avoids some auxiliary MH > combinator generation during bootstrap. > > Additional cleanups and refactoring further reduce bootstrap overhead and > number of classes loaded.
