[PATCH] D14164: Driver: fallback to parent directory of clang if no sysroot for mingw-w64 target

[Martell Malone via cfe-commits]

martell added a comment.

I tried adding a test case but I couldn't see how to control getInstalledDir from LIT.
It is a bit redundant because this was already true for windows and there was no test case for that.
After trying to create one I saw why :)

I missed to formatting so I updated it in http://reviews.llvm.org/rL253899
