Issue Description:

I have the following test file:

import Foundation
let url = URL(fileURLWithPath: "url.swift")
print("created, printing...")
print("\(url)")

When running this on armv7 architecture (Pi3 / raspbian stretch), it sometimes segfaults:

pi@pi3:~ $ swift url.swift
created, printing...
/home/pi/url.swift

pi@pi3:~ $ swift url.swift
created, printing...
Stack dump:0. Program arguments: /usr/bin/swift -frontend -interpret url.swift -disable-objc-interop -color-diagnostics -module-name urlSegmentation fault

Yikes. Obligatory warning that armv7 Linux is not a supported platform at this time, but someone's gonna need to look into it. (Well, unless it's already been fixed in Swift 4.2.)

I'm now using a build created from 4.1.2 by the ARM community and this issue doesn't appear. However due to the amount of patches applied, I'm not sure if this is fixed in master.
