Tentative and very experminental support for typerex. Enabled with

./configure -typerex .

It causes (non-fatal) errors when compiling files without a .mli (the problem
seems to have something to do with the flag -intf-suffix .cmi).

In practice, most typerex functionalities don't work well because typerex
fails its lookup into files compiled with -rectypes.
