[PATCH] D62493: [Driver] Always use Unix-style paths in the Darwin driver

[Louis Dionne via Phabricator via cfe-commits]

ldionne added a comment.

A few notes:

- I did setup a Windows machine and run the tests on it
- I'd welcome a better way to solve this problem than ripping out the use of `llvm::sys::path::append`, but I wasn't able to find anything in `FileCheck` that would do it
