Supporting old GHC versions in our libraries

We plan to support building our libraries, wherever possible (in particular, it will not be possible for the wired-in packages), with the same set of GHC versions that we support building GHC with.
We need to:
- Write down our supported GHC version policy for libraries in the appropriate place.
- Make the nightly builders test building the libraries with the bootstrapping compiler, so that regressions are detected.
- Add dependencies or other constraints to the libraries so that cabal won't try to use a library with an older compiler.
