Issue Description:
Hitting a swiftc crash in all Swift versions I tried, the most recent being
$ /Library/Developer/Toolchains/swift-DEVELOPMENT-SNAPSHOT-2017-07-04-a.xctoolchain/usr/bin/swift --version
Apple Swift version 4.0-dev (LLVM 1a69f372ee, Clang 17f727b492, Swift 57f6a63a4c)
Target: x86_64-apple-macosx10.9
I'll also attach a couple of crash reports. The attached crash.swift reproduces the problem. It's not a truly minimal test case, I literally went to the original source (that I can't share here) and search&replaced words to be able to share it.
