[wg-camlp4] A set of synthetic use cases to help discussions

[Anil Madhavapeddy]

I've started approaching this from the other end by instrumenting OPAM
to log all the camlp4 invocations during a bulk build.

https://github.com/avsm/opam-camlp4-analysis/wiki

has the raw data of all the *.{cma,cmo,cmx} files mentioned during a
build, and the packages.

This data still needs cleanup, but there are definitely some extensions in
there I don't immediately recognise, so it would be useful to update your
(far more structured) list from this.
