val remove : InferIR.Tenv.t -> Prop.normal Prop.t -> InferIR.Sil.atom -> Prop.normal Prop.t: Remove an attribute

val remove_for_attr : InferIR.Tenv.t -> Prop.normal Prop.t -> InferIR.PredSymb.t -> Prop.normal Prop.t: Remove all attributes for the given attr

val replace_objc_null : InferIR.Tenv.t -> Prop.normal Prop.t -> InferIR.Exp.t -> InferIR.Exp.t -> Prop.normal Prop.t: replace_objc_null lhs rhs. If rhs has the objc_null attribute, replace the attribute and set the lhs = 0

val nullify_exp_with_objc_null : InferIR.Tenv.t -> Prop.normal Prop.t -> InferIR.Exp.t -> Prop.normal Prop.t: For each Var subexp of the argument with an Aobjc_null attribute, remove the attribute and conjoin an equality to zero.
