It turns out that r280589 introduced a piglit regression that needs this
change to be applied already now rather than as part of later WQM rework.

I had originally planned this after https://reviews.llvm.org/D22195, but with the recent changes to
control flow lowering that other patch is currently not ready to land / be
adapted, so I adjusted this SCC fix patch so that it applies on current SVN
trunk.
