68f69ebdcc i965: Use is_scheduling_barrier instead of schedule_node::is_barrier.
Commit a73116ecc6 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.

700bebb958 i965: Move the back-end compiler to src/intel/compiler
Mostly a dummy git mv with a couple of noticable parts:
 - With the earlier header cleanups, nothing in src/intel depends
files from src/mesa/drivers/dri/i965/
 - Both Autoconf and Android builds are addressed. Thanks to Mauro and
Tapani for the fixups in the latter
 - brw_util.[ch] is not really compiler specific, so it's moved to i965.

v2:
 - move brw_eu_defines.h instead of brw_defines.h
 - remove no-longer applicable includes
 - add missing vulkan/ prefix in the Android build (thanks Tapani)

v3:
 - don't list brw_defines.h in src/intel/Makefile.sources (Jason)
 - rebase on top of the oa patches
