[Mesa-dev] [PATCH 1/4] tgsi: set nonhelpermask for vertex shaders

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

For atomic operations we really need to avoid executing unnecessary shaders, so for some
tests that just draw a single point we only want one vertex to get processed not 4,

this fixes a number of the atomic counters tests.
