Subject: [PATCH] nir/gather_info: Clear cross-invocation output mask.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Similar to how other I/O info is cleared at the beginning
of gather_info we should also clear the cross-invocation
mesh shader output mask.
