ab6d792986 intel/compiler: Pass detailed dependency classes to invalidate_analysis()
Have fun reading through the whole back-end optimizer to verify
whether I've missed any dependency flags -- Or alternatively, just
trust that any mistake here will trigger an assertion failure during
analysis pass validation if it ever poses a problem for the
consistency of any of the analysis passes managed by the framework.

d966a6b4c4 intel/compiler: Introduce backend_shader method to propagate IR changes to analysis passes
The invalidate_analysis() method knows what analysis passes there are
in the back-end and calls their invalidate() method to report changes
in the IR.  For the moment it just calls invalidate_live_intervals()
(which will eventually be fully replaced by this function) if anything
changed.

This makes all optimization passes invalidate DEPENDENCY_EVERYTHING,
which is clearly far from ideal -- The dependency classes passed to
invalidate_analysis() will be refined in a future commit.

e8f863e718 intel/compiler: Re-prefix non-logical surface opcodes with VEC4
The scalar back-end uses SHADER_OPCODE_SEND for all surface messages so
we no longer need the non-logical opcodes there.  Prefix them VEC4 so
it's clear that they're only used by the vec4 back-end.

a553eb0fdf i965: Support copy propagating of untyped atomic surface indexes.
In the vec4 backend, SHADER_OPCODE_UNTYPED_ATOMIC's src[1] is the
surface index.  We want to copy propagate so we can use an immediate
message descriptor, rather than an indirect send.

6e3265eae5 i965/vec4: split VEC4_OPCODE_FROM_DOUBLE into one opcode per destination's type
This way we can set the destination type as double to all these new opcodes,
avoiding any optimizer's confusion that was happening before.

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
