[PATCH] D66143: Don't use std::errc

[Alexey Bataev via Phabricator via cfe-commits]

ABataev added a comment.

Also, there is a clang unit test that fails because of the same reason. Can I include the changes in this test into this patch too or better to make a separate patch? The test is `unittests/Basic/FileManagerTest.cpp`
