st/nine: Queries: Fix D3DISSUE_END behaviour.

Issuing D3DISSUE_END should:
. reset previous queries if possible
. end the query

Previous behaviour wasn't calling end_query for
queries not needing D3DISSUE_BEGIN, nor resetting
previous queries.

This fixes several applications not launching properly.

i965/skl: Fix SBE state upload code.

effect of this is we're likely to get the default swizzle values, which disables

i965: Rename CACHE_NEW_*_PROG to BRW_NEW_*_PROG_DATA.

Now that we've moved a bunch of CACHE_NEW_* bits to BRW_NEW_*, the only
ones that are left are legitimately related to the program cache.  Yet,
it seems a bit wasteful to have an entire bitfield for only 7 bits.

State upload is one of the hottest paths in the driver.  For each atom
in the list, we call check_state() to see if it needs to be emitted.
Currently, this involves comparing three separate bitfields (mesa, brw,
and cache).  Consolidating the brw and cache bitfields would save a
small amount of CPU overhead per atom.  Broadwell, for example, has
57 state atoms, so this small savings can add up.

CACHE_NEW_*_PROG covers the brw_*_prog_data structures, as well as the
offset into the program cache BO (prog_offset).  Since most uses refer
to brw_*_prog_data, I decided to use BRW_NEW_*_PROG_DATA as the name.

Removing "cache" completely is a bit painful, so I decided to do it in
several patches for easier review, and to separate mechanical changes
from manual ones.  This one simply renames things, and was made via:

$ for file in *.[ch]; do
      sed -i -e 's/CACHE_NEW_\([A-Z_\*]*\)_PROG/BRW_NEW_\1_PROG_DATA/g' \
             -e 's/BRW_NEW_WM_PROG_DATA/BRW_NEW_FS_PROG_DATA/g' $file
  done

Note that BRW_NEW_*_PROG_DATA is still in .cache, not .brw!
The next patch will remedy this flaw.  It will also fix the
alphabetization issues.

util/u_atomic: Fix the unlocked implementation.

It was totally broken:

- p_atomic_dec_zero() was returning the negation of the expected value

- p_atomic_inc_return()/p_atomic_dec_return() was
  post-incrementing/decrementing, hence returning the old value instead
  of the new

- p_atomic_cmpxchg() was returning the new value on success, instead of
  the old

It is clear this never used in the past. I wonder if it wouldn't be better to
yank it altogether.

util/u_atomic: Add a simple test.

It was much easier for me to verify things build and run as expected
with this simple test, than building and testing whole Mesa.

With scons the test can be build and run merely by doing:

Building the test with autotools is left as a future exercise.

util: Make u_atomic.h typeless.

like how C11's stdatomic.h provides generic functions. GCC's __sync_*
builtins already take a variety of types, so that's simple.

MSVC and Sun Studio don't, but we can implement it with something that
looks a little crazy but is actually quite readable.

vc4: Introduce scheduling of QPU instructions.

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%)

vc4: Drop the explicit scoreboard wait.

This is actually implicitly handled by the TLB operations.

vc4: Also deal with VPM reads at thread end.

Prevents a regression with QPU scheduling, which happens to put the no-op
reads for unused VPM contents end up at the end of the program.

vc4: Fix assertion about SFU versus texturing.

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.

vc4: Add another check for invalid TLB scoreboard handling.

This was caught by an assertion in the simulator.

freedreno/a4xx: invalidate cache when vbo's change

Otherwise vertex shader can see stale cache data.  This in particular

issues, but seems safest to flush whenever new vertex buffers are bound.
