For now, this just splits the existing code to disable these stages into
separate atoms/files. We can then replace it with real code.
v2: Bump the render atoms in this patch so it compiles (in my branch,
I'd bumped it in an earlier patch). 61 seems to be the minimum
that works, which doesn't match the old value + the number of atoms
I added in this patch, so apparently we had some slop before.
v3: Actually disable the DS unit on Gen8+.

This patch implements the binding table enable command which is also
used to allocate a binding table pool where where hardware-generated
binding table entries are flushed into. Each binding table offset in
the binding table pool is unique per each shader stage that are
enabled within a batch.
Also insert the required brw_tracked_state objects to enable
hw-generated binding tables in normal render path.
v2: - Use MOCS in binding table pool alloc for GEN8
- Fix spurious offset when allocating binding table pool entry
and start from zero instead.
v3: - Include GEN8 fix for spurious offset above.
v4: - Fixup wrong packet length in enable/disable hw-binding table
for GEN8 (Ville).
- Don't invoke HW-binding table disable command when we dont
have resource streamer (Chris).
v5: - Reorder the state cache invalidate flush so it happens in-between
enabling hw-generated binding tables and the previous sw-binding
table GPU state (Chris).
v6: - Do the same fix in v5 for gen7_disable_hw_binding_tables().
- Adhere to coding guidelines and make comments more informative.

It's been merged into brw_state_flags::brw for simplicity and
efficiency.

v2: Do not attempt to share the code that uploads
3DSTATE_BINDING_TABLE_POINTERS_GS, 3DSTATE_SAMPLER_STATE_POINTERS_GS,
or 3DSTATE_GS with VS.

"ff" is for "fixed function". This frees up the name "gs" to refer to
user-defined geometry shaders.

This makes brw_context available in every function that used
intel_context. This makes it possible to start migrating fields from
intel_context to brw_context.
Surprisingly, this actually removes some code, as functions that use
OUT_BATCH don't need to declare "intel"; they just use "brw."

This reverts commit 6c966ccf07bcaf64fba1a9b699440c30dc96e732.
Apparently causes GPU hangs.

This removes a tiny bit of code from our drawing loop.

These don't need to be re-disabled on every batch if we're using
hardware contexts. (If we're not, this is equivalent.)

We'll be growing more code in here as we actually enable the unit.

There will be a little bit of thrashing of the program cache BO as the
cache warms up, but once the application is in steady state, this
reduces relocations on gen5 and later.
On my T420 laptop, cairogl firefox-talos-gfx performance improves 2.6%
+/- 1.3% (n=6). No statistically significant performance difference
on nexuiz (n=5).

This may not be necessary, but it seems like a good idea.
