[PATCH] D109621: [clang][Driver] Default to loading clang.cfg if config file not specified

[Michał Górny via Phabricator via cfe-commits]

mgorny added a comment.

As @sepavloff points out in the linked discussion, we probably need an option to disable loading default configuration files too, and we should use it in the test suite (via modifying the `%clang` substitutions, I guess), as otherwise someone enabling config file support is going to see random test failures.
