[PATCH] D15006: Driver: Better detection of mingw-gcc

[Martell Malone via Phabricator via cfe-commits]

martell added a comment.

To clarify the most import part about actually being able to test this is the being able to modify the PATH variable for windows and unix hosts in the test case.
The program prefix is less of a problem because I can double down with the same empty file one with .exe and one without.
Just thought that I would note it incase someone has ran into this already.
