Would it be possible to not need to propagate `IntraTileHint` through multiple functions, but instead make `checkOpenMPIterationSpace` find it itself? For instance `Stmt *S` can be that AttributedStmt. If so, extract the `OMPInvariantPredicateBoundAttr` and continue with the Stmt that S had attributed.
