Bouke, mind checking if compiling with swiftc works, instead of directly running the code with swift?

@swift-ci create

Not sure why it failed initially, but I cannot reproduce. Both `swift` and `swiftc` compile the code listed just fine.

bouke@ubuntu:~$ swiftenv which swift
/home/bouke/.swiftenv/versions/4.0-DEVELOPMENT-SNAPSHOT-2017-08-21-a/usr/bin/swift
bouke@ubuntu:~$ cat foundation_data.swift
import Foundation
print(Data())

bouke@ubuntu:~$ swift foundation_data.swift
0 bytes
bouke@ubuntu:~$ swiftc foundation_data.swift
