This could really help #13623. My usecase is comparing token types. I don't care what the contents are, and I don't want to write an explosive combinatorial match to do so.

Won't the strategy used in #15503 work here?

Auto merge of rust-lang#16307 - Veykril:vfs2, r=lnicola
c1c2421 
internal: VFS no longer stores all source files in memory

Turns out there is no need to keep the files around. We either upload them to salsa once processed, or we need to keep them around for the `DidChangeTextDocumentNotification`, but that notification is only valid for opened documents, so instead we can just keep the files around in the `MemDocs`!

Fixes rust-lang/rust-analyzer#16301
