Matthew Simpson b65c230eab [LV] Ensure reverse interleaved group GEPs remain uniform 
For uniform instructions, we're only required to generate a scalar value for
the first vector lane of each unroll iteration. Thus, if we have a reverse
interleaved group, computing the member index off the scalar GEP corresponding
to the last vector lane of its pointer operand technically makes the GEP
non-uniform. We should compute the member index off the first scalar GEP
instead.

I've added the updated member index computation to the existing reverse
interleaved group test.
