GHC 8.0.2 status

Hi Ben,

while in the eye of the cyclone, as we're waiting for these last few OS X
issues to clear up... I was wondering, do you currently have a means to
"vet" release candidates before cutting a new release?

More to the point, to check that a point release like these doesn't include
any breaking changes it might be useful to try compiling all of Stackage
with it, even if it's just once, much like the Stackage curators do. As you
may have seen a few hours ago, e.g. singletons doesn't compile using the
current GHC 8.0.2 candidate (tip of ghc-8.0 branch). It did compile just
fine using 8.0.1. And FWIW it also compiles okay with GHC HEAD.

Likely this has been discussed before. So I'm just enquiring about status
regarding adding this item in the workflow.
