i965: Alphabetize brw_tracked_state flags and use a consistent style.

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.

i965: Combine CACHE_NEW_*_UNIT into BRW_NEW_GEN4_UNIT_STATE.

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.

i965: Fold the gen7_cc_viewport_state_pointer atom into brw_cc_vp.

These always happen together; the extra atom just means another item to
iterate through, flags to check, and a call through a function pointer.

i965: Move CACHE_NEW_*_VP flags to BRW_NEW_*_VP.

We've been streaming these out for ages, so they basically have nothing
to do with brw_state_cache.c.

Saves 6 * sizeof(void *) bytes per context, as we won't have useless
aux_compare/aux_free functions for them.

i965: Move some /* CACHE_NEW_SAMPLER */ comments.

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.

i965: Move CACHE_NEW_SAMPLER to BRW_NEW_SAMPLER_STATE_TABLE.

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.

While we're at it, rename BRW_WM_PROG to BRW_CACHE_FS_PROG, to move away
