This doesn't reschedule much currently, just tries to fit things into the
regfile A/B write-versus-read slots (the cause of the improvements in
shader-db), and hide texture fetch latency by scheduling setup early and
results collection late (haven't performance tested it). This
infrastructure will be important for doing instruction pairing, though.
shader-db2 results:
total instructions in shared programs: 61874 -> 59583 (-3.70%)
instructions in affected programs: 50677 -> 48386 (-4.52%)
We're supposed to be checking that nothing else writes r4, which is done
by the TMU result collection signal, not the coordinate setup.
Avoids a regression when QPU instruction scheduling is introduced.
Otherwise vertex shader can see stale cache data. This in particular
happens when the same vbo is updated and reused. Not sure yet if vbo's
at differing addresses but bound to same vertex buffer slot could have
issues, but seems safest to flush whenever new vertex buffers are bound.

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.

Marking brw_stage_state::sampler_count as CACHE_NEW_SAMPLER is wrong.
The number of samplers used by each program is actually computed at
draw time (brw_try_draw_prims), based purely on the currently bound
shader programs (gl_program::SamplersUsed).
CACHE_NEW_SAMPLER means that we've emitted a new SAMPLER_STATE table.
Although this could indicate that the number of samplers has changed,
it could also simply mean that the contents of the table has changed
(i.e. we've bound different textures).
The real reason these atoms depend on CACHE_NEW_SAMPLER is because they
include a pointer to the SAMPLER_STATE table. This was not commented.
So, move the comments to the appropriate place.

On Gen4-5, unit state is specified as indirect state, rather than
commands. If any unit state changes, we upload it via brw_state_batch
and arrange for 3DSTATE_PIPELINED_POINTERS to be re-emitted, which
updates pointers to all unit state at once.
Since there's only one command and state atom (brw_psp_urb_cs) that
needs to know about this, there's no benefit to having six separate
flags. We can combine CACHE_NEW_*_UNIT into a single flag.
We also haven't cached these in a long time, so it doesn't make sense
to use the "CACHE_NEW_" prefix. Instead, use the "BRW_NEW_" prefix.
This also saves 12 * sizeof(void *) bytes of memory per context, as
we remove useless aux_compare/aux_free functions for each CACHE bit.

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

This patch settles on one flag per line, in alphabetical order, using
spaces instead of tabs, and sheds the unnecessary parentheses.

When using MRT on Gen4-5, we have to simulate GL's alpha test feature
by emitting discards in the fragment shader. In this case, it makes
sense to set prog_data->uses_kill, which means the fragment shader may
kill pixels via the discard mechanism.
This saves us from having to look an extra key value in a couple of
places, including in the generator.

Kristian noted that there's very little use of brw_wm_prog_key in the
generator, and that it basically just generates what it's told, without
caring about what stage it's handling.
One exception to this is derivative handling. When handling dFdxCoarse
and dFdxFine, we packed an enum value in a second source register,
explicitly telling the generator what to do. For dFdx, we specified an
enum value of "please use the hint", then checked the program key in the
generator level code.
A natural method is to define separate FS_OPCODE_DD[XY]_{COARSE,FINE}
opcodes, and have the front-end (which already decides what IR to
generate based on the program key) decide which dPdx/dPdy should
correspond to. This consolidates the decision making in one place.
