[PATCH] D26166: [Sema] Don't issue analysis-based warnings when a fatal error has occurred

[Richard Smith via cfe-commits]

rsmith added a comment.

It looks like the bug is that if we hit an uncompilable error after hitting a non-uncompilable fatal error (promoted from a warning), we fail to notice that we've hit an uncompileable error. Our AST should be complete if `hasUncompilableErrorOccurred()` is not set, and it looks like we're violating that invariant here.
