i965: Use is_scheduling_barrier instead of schedule_node::is_barrier.
Commit a73116ecc60414ade89802150b tried to make add_barrier_deps()
walk to the next barrier, and stop. To accomplish that, it added an
is_barrier flag. Unfortunately, this only works half of the time.
The issue is that add_barrier_deps() walks both backward (to the
previous barrier), and forward (to the next barrier). It also sets
is_barrier. Assuming that we're processing instructions in forward
order, this means that is_barrier will be set for previous instructions,
but not future ones. So we'll never see it, and walk further than we
need to.
dEQP-GLES31.functional.ssbo.layout.random.all_shared_buffer.23
now compiles its shaders in 3.6 seconds instead of 3.3 minutes.
