Support Swift 3.1

[felix91gr]

Or else I'm compiling something wrong.

This is my environment:

• OS: Linux, Elementary OS (based on Ubuntu 16.04 LTS)
• Toolchain: Swift version 3.1-dev (LLVM a7c680da51, Clang 9772bf511a, Swift ac7b7f3777)

I compiled the toolchain myself.

And this is how I tried to compile SourceKitten:

1. Ran this:

sudo echo >> ~/.bashrc
sudo echo export LINUX_SOURCEKIT_LIB_PATH='/build/swift-3.1-DEVELOPMENT-SNAPSHOT-2017-03-19-a/usr/lib/sourcekitdInProc.framework/sourcekitdInProc' >> ~/.bashrc

2. Relaunched the Terminal, cloned the repo and checkout-ed the latest release:

git clone https://github.com/jpsim/SourceKitten
cd SourceKitten/
git checkout tags/0.17.0

3. Tried to build it (here it failed)

error: the package has an unsupported layout, modulemap (/home/felix/Desktop/other-scripts/SourceKitten/Source/SourceKittenFramework/clang-c/module.modulemap) is not allowed to be mixed with sources
fix: move the modulemap inside include directory

I think either I did some step wrong, compiled or configured the Swift toolchain badly, or SourceKitten doesn't support Swift 3.1 yet 🤔

The problem here is that you need this fix, which happened after the 0.17.0 tag. I'm hoping we can convince @jpsim to tag a new release for this 😄

Hi all, I haven't tried building SourceKitten with Xcode 8.3 final yet, and from what I can tell from #352, there are quite a few things that need updating to fully support Xcode 8.3. So let's keep this open until all those can be addressed.

Sorry the part I'm mentioning applies for Swift 3.0 as well.
