relates to:

• SR-11033 Add option in Swift driver to disable color diagnostics

Issue Description:

Swiftc outputs nice colored text with it's error messages. The swift package manager, when run with 'swift run', outputs uncolored text except for the last line, which it adds to the swiftc output.

I'm running on Ubuntu 16.04.

The compiler currently has an internal option to force color diagnostics even when output is being captured, but no driver-level option. It would be easy to add, though.

I believe this was fixed by apple/swift-package-manager#1391

@belkadan We're using `-Xfrontend -color-diagnostics` to force the color, let me know if that is incorrect.

[belkadan]

Well, SwiftPM shouldn't really rely on frontend options. It's not wrong but it could be more right. Maybe this bug could be used to add support to the compiler driver and get SwiftPM to drop the -Xfrontend?

[aciidb0mb3r]

Sure!

Yep! This was fixed by updating to the non-release version of swift.
