[wg-camlp4] Changes to the parsetree

[Anil Madhavapeddy]

There is no such OPAM remote at the moment, but I think it would be good to add one and move out some of the more experimental branches (e.g. allocation-profiling) from the main OPAM repo.

Thomas, any objections to me doing this rearrangement in OCamlPro/opam-repository?

Supporting range patterns directly in the compiler would add a little bit of extra complexity for type-checking (exhaustiveness check) and code generation.  I don't see any theoretical problem, though.
