Automated rollback of commit 09f26fdadfad0e2e5fed4f377b564213d894bf49. *** Reason for rollback *** Only change to the include scanner, potentially the culprit of b/175294870 *** Original change description *** Reduce needless contention in the include scanner's fileParseCache. The computeIfAbsent() function of ConcurrentHashMap is supposed to have a fast implementation and the map will then allow ~number of processors concurrent writes. However, reading a file and extracting the include lines can be a costly IO operation that does not fit this bill. Use futures instead. RELNOTES: None. PiperOrigin-RevId: 346800721
