Issue Description:

If I have versioned package manifests such as

Package.swift // swift-tools-version:4.2
Package@swift-3.1.swift
Package@swift-4.swift

There is currently no way to make `swift test` in previous-version compatibility mode so as to test behaviour in every case – this is obviously useful for a library that might be included by another package that itself still builds using a compatibility mode.

The workaround is obviously to manipulate and rename package manifests, but that is less than desirable.

Forgive my denseness, but I don't see what the solution was here.

I still can't figure out how to make the swift 5 tools run my test in 4.2 mode without juggling manifests. I really thought the following (or something equivalent) would become a possibility:

swift test ``-swift-version 4.2

After all this time, I tried the terrible:

swift test -Xswiftc -swift-version -Xswiftc 4.2

And that's the thing that works.

Ouch!
