The aim of this patch is to refactor how we handle and report error. I suggest to use the same approach we use in LLD: delayed error reporting. For that I introduced 'HasError' flag which triggers when we report an error. Now we do not exit instantly on any error. The benefits are: 1) There are no more 'exit(1)' calls in the library code. 2) Code was simplified significantly in a few places. 3) It is now possible to print multiple errors instead of only one. Also, I changed the messages to be lower case and removed a full stop. Differential revision: https://reviews.llvm.org/D67182 llvm-svn: 371380
