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

This flag signifies that we've emitted a new SAMPLER_STATE table.
Given that we haven't cached those in years, CACHE_NEW_SAMPLER isn't
a great name. Putting it in the BRW_NEW_* hierarchy would make more
sense; BRW_NEW_SAMPLER_STATE_TABLE better reflects its actual purpose.
When this flag is raised, the pointer to the SAMPLER_STATE table has
changed, so we need to re-issue any packets which point to it (unit
state on Gen4-5, 3DSTATE_SAMPLER_STATE_POINTERS on Gen6, and the
per-stage variants on Gen7+).
Saves 2 * sizeof(void *) bytes per context, as we remove useless
aux_compare/aux_free function pointers.

Most of the dirty flags were listed in some arbitrary order. Some used
bonus parenthesis. Some put multiple flags on one line, others put one
per line. Some used tabs instead of spaces...but only on some lines.
This patch settles on one flag per line, in alphabetical order, using
spaces instead of tabs, and sheds the unnecessary parentheses.
Sorting was mostly done with vim's visual block feature and !sort,
although I alphabetized short lists by hand; it was pretty manual.

This paves the way for sharing the code that will set up the vertex
and geometry shader pipeline state.

Also upload separate sampler default/texture border color entries.
At the moment, this is completely idiotic: both tables contain exactly
the same contents, so we're simply wasting batch space and CPU time.
However, soon we'll only upload data for textures actually /used/ in
a particular stage, which will usually make the VS table empty and
very likely eliminate all redundancy. This is just a stepping stone.

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."

We already program all the sampler state correctly, we just didn't give
the GPU a pointer to it for the VS stage. Thus, any texturing other
than texelFetch() wouldn't work.
Fixes piglit test vs-textureLod-miplevels and 99 of oglconform's
glsl-bif-tex subtests.
NOTE: This is a candidate for the 8.0 branch.

brw_wm_samplers actually enables any active samplers regardless of what
pipeline stage is using them, so it doesn't make much sense for it to be
WM-specific. So, rename it to "brw_samplers."
To properly generalize it, move sampler_count and sampler_offset from
brw_context::wm to a new brw_context::sampler that can be shared without
looking strange.

This was a requirement we didn't run into until we started using
STATE_BASE_ADDRESS for instruction data.

Now that all the dynamic state is streamed through the top of the
batchbuffer, we can cut out many of our relocations to that state by
using the base address.

Overall, across this series since the last set of numbers, gen6 3DMMES
taiji performance has dropped 0.8% +/- 0.3% (n=15), probably due to
the increased reissuing of state from some of the state objects that
otherwise never changed, and increased occurrence of the per-batch
overhead as we've increased how much we put in the batch BO without
increasing the batch BO's size.

This should make it easier to cross-reference the code and hardware
documentation, as well as clear up any confusion on whether constants
like CMD_3D_WM_STATE mean WM_STATE (pre-gen6) or 3DSTATE_WM (gen6+).
This does not rename any pre-gen6 defines.

These were for debugging in bringup. Now that relatively complicated
apps are working, they haven't helped debug anything in quite a while.

The modify bit is now usually in the instruction header. The
exception is CC state pointers.
