Jason Ekstrand 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
