Extraction: re-introduce some eta-expansions in rare situations leading to '_a types
If there's no lambdas at the top of a constant body
and its type is functional
and this type contains type variable
and we're extracting to Ocaml
then we perform one eta-expansion to please the ML type-checker
This might slow down things, if some computations are shared
thanks to the partial application. But it seems quite unlikely to
encounter both situations (clever partial application and
non-generalizable variable) at the same time. Compcert is ok,
for instance.
As a consequence, no need for manual eta-expansion in AVL code
(and by the way MSetAVL.element wasn't a problem, it is monomorphic)
