To reproduce:
1. Install latest GM/Beta Xcode
2. $ git clone git@github.com:apple/swift-source-compat-suite.git
3. $ cd swift-source-compat-suite
To build Swift from scratch before testing:
4. $ ./reproduce.py master --project-path CoreStore
Or if you've already built Swift:
4. $ ./reproduce.py master --project-path CoreStore --swiftc path/to/swiftc
