(** [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.
