Currently, the LowerConstantIntrinsics pass does an RPO traversal of every function... only to find that many functions don't have constant intrinsics (is.constant, objectsize). In the CodeGen pipeline, there is already a pre-isel intrinsic lowering pass, which iterates over intrinsic declarations and lowers all users. Call lowerConstantIntrinsics from this pass to avoid the extra iteration over the entire IR and the RPO traversal.
