const_prop defs ref_vars substs assigns exp performs constant propagation on exp where substs is a pair of substitutions on immutable variables and type variables, assigns is a substitution on mutable variables, and ref_vars is the set of variable which may have had a reference taken (and hence we cannot reliably track).
