const_*_expr expr v annot, where the expression expr is known to evaluate to the value v, attempt to produce a more simple expression together with its approximation and the benefit gained by replacing expr with this new expression. This simplification is only performed if expr is known to have no side effects. Otherwise, expr itself is returned, with an appropriate approximation but zero benefit.

const_boxed_int_expr takes an additional argument specifying the kind of boxed integer to which the given expression evaluates.
