During the modifications of the passes on `Ast_typed`, the binding
environments are not kept in sync. To palliate this, this module
recomputes them from scratch.

This module is very coupled to `typer.ml`. Given environments are
not used until the next pass, it makes sense to split this into
its own separate pass. This pass would go from `Ast_typed` without
environments to `Ast_typed` with embedded environments.
