Inconstant_identsval inconstants_on_program : compilation_unit:Compilation_unit.t -> backend:(module Backend_intf.S) -> Flambda.program -> resultinconstants_on_program finds those variables and set-of-closures identifiers that cannot be compiled to constants by Flambda_to_clambda.
val variable : Variable.t -> result -> boolvariable var res returns true if var is marked as inconstant in res.
val closure : Set_of_closures_id.t -> result -> boolclosure cl res returns true if cl is marked as inconstant in res.
