We have written a couple of patches to fix these tests:

$ git clone -b wip/siglesias/chv-fixes https://github.com/samuelig/mesa.git

The fixes are specific to Cherryview, so they might be failing in BXT. There is
one patch from Kenneth that did not land master but it is still in my branch.
With these patches I got 0 piglit regressions on BSW and BDW and the remaining
fp64 failed tests on BSW are fixed.

Mark, Would you mind testing them in CI system? Our plan is to land them in
master before the 4th release candidate (planned on Friday, AFAIK), so they
will part of the final 12.0 release.

Thanks!
