[PCH] When serializing Stmts, keep track of when sub statements are referenced again and in such a case just write out a reference of a previously serialized Stmt, instead of serializing it all over again. This saves memory + space + [de]serializing time, and avoids blowing up memory with pathological cases. rdar://10293911 llvm-svn: 142696
