This adds the necessary veneer in Asmgen for Flambda 2 compilation.

I don't understand why the compiler is unable to find Flambda2.Flambda_backend_intf and Flambda2.Flambda_middle_end. However referencing them via their mangled names works; I think this is a question for another day.

Ah, I think I have found the problem with the module names -- the library Flambda2_backend_impl was accidentally named Flambda_backend_intf.

...although that doesn't actually fix it. Let's leave this minor problem for now.

In "middle_end/flambda2/dune", there is an (include_subdirs unqualified)
stanza, and then in a subdirectory ("backend_intf/"), there is a "dune" file
with a (include_subdirs no). I am surprised (and confused) to see dune
accept that some files (namely "middle_end/flambda2/backend_intf/flambda2_backend_intf.ml{,i}")
are part of two libraries simultaneously.

I am not claiming this explains the issue you reported, but that feels weird.

Yeah I am just investigating further, and I do suspect this might be the source of the problem. I will fix it in the next PR.

And I don't think you can have Flambda2.Flambda_backend_intf
without any public names.
