[swift-build-dev] Building custom toolchain

FWIW, this:
https://gist.github.com/ddunbar/598bf66952fba0e9d8aecc54995f018e
is the script I currently use on OS X to get a working "swift-dev.xctoolchain" out of a built Swift. It isn't designed to work for anyone but me, but it should be easy to adapt.
I always run this after every build, and then use `TOOLCHAINS=swift-dev swift build` (etc) to use the development compiler.
My "toolchain-based build process" proposal will hopefully make this a no-op.
