[PATCH] D68164: [Commandline] Clear error on raw_ostream when there is parsing error.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

So, could you add a testcase to demonstrate the issue?

If an error occurs, I believe this piece of code will try to call report_fatal_error and that will fail too for the same reason (because if the code fails, it is likely that we can't write anything to stderr), and the process will exit with exit code 1. So, is the new behavior implemented in this patch distinguishable from the existing behavior? If a command behaves differently with this patch, please add a test to demonstrate it.
