* DiagnosticsEngine should clear DelayedDiagID before reporting theAlex Lorenz2017-05-041-0/+29
| | | | | | | | | | | | | | | | | | | | | delayed diagnostic This fix avoids an infinite recursion that was uncovered in one of our internal tests by r301992. The testcase is the most reduced version of that auto-generated test. This is an improved version of the reverted commit r302037. The previous fix actually managed to expose another subtle bug whereby `fatal_too_many_errors` error was reported twice, with the second report setting the `FatalErrorOccurred` flag. That prevented the notes that followed the diagnostic the caused `fatal_too_many_errors` to be emitted. This commit ensures that notes that follow `fatal_too_many_errors` but that belong to the diagnostic that caused `fatal_too_many_errors` won't be emitted by setting the `FatalErrorOccurred` when emitting `fatal_too_many_errors`. rdar://31962618 llvm-svn: 302151
