Summary: - when we hit the cache, the reported filename should be that of the cache query, not that of the cache store. This matches behaviors of common FSes, and avoids triggering difficult edge cases in FileManager when files are being moved around concurrently. - filename comparisons (both cache queries and == mainfile checks) should fold away . and .. in paths. These can appear when relative paths occur in compile_commands.json. (gn does this).
