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

[Yaron Keren via cfe-commits]

This always searches for something-gcc and then discards the result if sysroot was provided, which is a waste.
Move the searching to a helper function and then it can be done only if sysroot was not provided, as it is now.

The break is needed to avoid looking for mingw32-gcc after x86_64-w64-mingw32-gcc was already found. It's a wasted search.
