This series fixes these two related bugs:


The first bug has had a fix for a while but until now I wasn't able to
figure out what to do on BDW. I had previously made a fix for the
second bug but as pointed out by the original bug reporter the two
bugs interact and the fixes would conflict. This series has a v2 of
the patch so that the two fixes work together.

I've posted a patch to make the Piglit testing more thorough here:


In the v1 for patch 3 Chris Forbes had a comment that it would be
better to move the edge flag element within brw->vb.* instead of while
emitting the state. I think this would be a good idea except it won't
help in this case now that it works with the SGVS element as well
because there is no input for that at all in brw->vb.*.
