Enable GHC to be loaded into GHCi
It would be very helpful for development to be able to load GHC itself into GHCi. In principle this shouldn't be so hard since GHC is just another Haskell program. However, in practice there are a number of modules which use unboxed tuples, which the interpreter does not support. However, it should be possible to the convince GHC to use object code for just these modules and interpret the rest. I have a few attempts at this here (https://gist.github.com/bgamari/bd53e4fd6f3323599387ffc7b11d1a1e).
