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.

now compiles its shaders in 3.6 seconds instead of 3.3 minutes.

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
