Issue Description:

This is a compiler crash that I discussed at WWDC 2017 with Doug Gregor and Phillipe Hausler.

The simplest repro case I've found is at https://github.com/carlbrown/CorelibsCompilerCrash

If you comment out the `X` from the last line of `main.swift`, it will compile. If you leave it in, you get the following crash:

Comment by Carl Brown (JIRA)

Just to set the stage - what I'm trying to do is make it easier for people (like me) to link apps against SwiftFoundation on the Mac. This way we can use the Mac's MUCH BETTER tools (Instruments.app FTW) to profile and fix bugs in swift-corelibs-foundation.

This bug makes it REALLY hard, because any syntax error causes a compiler crash instead of an error message, so work takes forever.
