Thank you! Until Travis CI supports Xcode 9.3,

Hello, thank you for the change.

In order to land this, you'll need to update the Travis build script to point at Swift 4.1. Before you do that, I have a request: #95 is where we disabled the Linux build because of an unfortunate oversight in the build script. If you could, let me know if you'd be willing to look into re-enabling that build configuration for 4.1. It's entirely optional, but it would be a huge help if you could.

sure i can definitely take a look at the travis build script.

Holy cow, that worked like a charm. ✨

Thank you so very very much. I'm going to release this as a new version of LLVMSwift.
