Force index/loop validation on the D3D9 backend D3D9 shader models have limited support for looping, so the Appendix A index/loop limitations are necessary. This is consistent with applying the limitations on D3D9_3 feature level and lower of the D3D11 backend too. Also, when the limitations are not in place, a workaround for dynamic indexing of vectors and matrices will be applied. This workaround does not work on the D3D9 backend, as demonstrated with some WebGL conformance failures caused by it in Chrome on D3D9.
