Sourceval opt_smt_linearize : bool ref

Some of the code in the environment needs to use the smt solver, which is defined below. To break the circularity this would cause (as the prove code depends on the environment), we add a reference to the prover to the initial environment.

Sourceval empty : t

This should not be used outside the type checker, as initial_env sets up a correct initial environment.
