[Preprocessor] Don't avoid entering included files after hitting a fatal error. Change in r337953 violated the contract for `CXTranslationUnit_KeepGoing`: > Do not stop processing when fatal errors are encountered. Use different approach to fix long processing times with multiple inclusion cycles. Instead of stopping preprocessing for fatal errors, do this after reaching the max allowed include depth and only for the files that were processed already. It is likely but not guaranteed those files cause a cycle. rdar://problem/46108547 Reviewers: erik.pilkington, arphaman Reviewed By: erik.pilkington Subscribers: jkorous, dexonsmith, ilya-biryukov, Dmitry.Kozhevnikov Differential Revision: https://reviews.llvm.org/D55095 llvm-svn: 348641
