; In case the pieceweise affine function used to create an isl_ast_expr
; had empty cases (e.g., with contradicting constraints on the
; parameters), it was possible that the condition of the isl_ast_expr
; select was not a comparison but a constant (thus of type i64).
; However, we shouldn't crash in such a case :)
