Sync now uses a callback to ensure that it's called by the last
thread moving past a DC. This will help with the new counter
handling.

This works out to be a wash in terms of memory usage: We use more memory
to store the separate ALU instructions, but we optimize out a lot of code
as well. The main result, though, is that we do more of our work at link
time rather than draw time.
We don't want to bake the whole array into the FS key, because of the
hashing overhead. But we can keep a set of the arrays seen, and use a
pointer to the copy in as the array's proxy.
Between this and the previous patch, gl-1.0-blend-func now passes on
hardware, where previously it was filling the 256MB CMA area with shaders
and OOMing.
Drops 712 shaders from shader-db.
Without this, the X server may accumulate stale Present event contexts
if a client performs several video decoding sessions using the same
window.
v2: Based on Chris Wilson's review:
* Use xcb_discard_reply() instead of free(xcb_request_check())

We were baking in the LOD of the source level to each shader. Instead,
pass it in as a uniform -- this requires storing it to a temp register,
but that's better than compiling a ton of separate shaders:
total instructions in shared programs: 115032 -> 115036 (0.00%)
instructions in affected programs: 96 -> 100 (4.17%)
LOST: 572
This helps in debugging memory pressure. It would be nice if we could
tell valgrind about it all the way from allocation time to destroy, but we
need a pointer to hand to VALGRIND_MALLOCLIKE_BLOCK.
The ranges are in units of bytes, not dwords. This wasn't caught by
piglit tests because ttn tends to make one big uniform file, so we only
had one UBO range with a src and dst offset of 0.
v_fma_f32 runs at FP64 rate (= slow). Alien Isolation and F1 2015 seem
to use fma for all d3d multiply-add instructions, which is silly.
This tries to restore performance for those games.
The main difference between v_mad_f32 and v_fma_f32 is that v_mad doesn't
support denormals, which we don't enable anyway, because they are slow too.
Also, there is code size reduction:
Totals from affected shaders:
VGPRS: 109796 -> 109808 (0.01 %)
Spilled SGPRs: 29995 -> 30022 (0.09 %)
Spilled VGPRs: 12 -> 13 (8.33 %) <-- it's just one shader going from 12 to 13
Code Size: 6667596 -> 6476356 (-2.87 %) bytes
Max Waves: 26931 -> 26899 (-0.12 %)
I've not actually tested real performance.
