Summary: Could be made better for cycles but not used and not unit tested, let's remove it.

Summary: Do not fail on cycles, normalize values issuing from cycles, but do not try to recognize equal cycles like `let rec x = 1 :: x` and `let rec y = 1 :: 1 :: y`. This is unlikely to happen in our code.

Summary:
The previous version had a potentially exponential behavior on values with already lots of sharing.
This is fixed here at the price of a multiplicative constant factor (cost of `Hashtbl.hash`).
It also prepares for the handling of cycles.

Summary:
Reduces the size of the `tenv` by sharing values as most as possible, in an untyped - but supposedly safe - way, by using black magic on objects.
Can be reused for other things later.
