i965: Implement transform feedback query support in hardware on Gen6+.

Now that we have hardware contexts and can use MI_STORE_REGISTER_MEM,
we can use the GPU's pipeline statistics counters rather than going out
of our way to count primitives in software.

Aside from being simpler, this also paves the way for Geometry Shaders,
which can output an arbitrary number of primitives on the GPU.  It will
also allow us to use hardware primitive restart when these queries are
in use.

The GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN query is easy: it
corresponds to the SO_NUM_PRIMS_WRITTEN/SO_NUM_PRIMS_WRITTEN0_IVB
counters.

The GL_PRIMITIVES_GENERATED query is trickier.  Gen provides several
statistics registers which /almost/ match the semantics required:
- IA_PRIMITIVES_COUNT
  The number of primitives fetched by the VF or IA (input assembler).
  This undercounts when GS is enabled, as it can output many primitives.
- GS_PRIMITIVES_COUNT
  The number of primitives output by the GS.  Unfortunately, this
  doesn't increment unless the GS unit is actually enabled, and it
  usually isn't.
- SO_PRIM_STORAGE_NEEDED*_IVB
  The amount of space needed to write primitives output by transform
  feedback.  These naturally only work when transform feedback is on.
  We'd also have to add the counters for all four streams.
- CL_INVOCATION_COUNT
  The number of primitives processed by the clipper.  This doesn't work
  if the GS or SOL throw away primitives for rasterizer discard.
  However, it does increment even if the clipper is in REJECT_ALL mode.

Dynamically switching between counters would be painfully complicated,
especially since GS, rasterizer discard, and transform feedback can all
be switched on and off repeatedly during a single query.

The most usable counter is CL_INVOCATION_COUNT.  The previous two
patches reworked rasterizer discard support so that all primitives hit
the clipper, making this work.

v2: Occlusion query bug fixes removed and squashed in earlier patches.

gallivm: handle z32s8x24 format for sampling

Since we can only sample either depth or stencil but not both only load
the required bits which makes things a bit easier (it requires special
handling since the format doesn't fit into 32bit).
The logic for deciding if depth or stencil should be sampled is a bit odd,
but seems to be what other drivers and statetrackers do: if it's a format with
both depth and stencil (or just with depth) then sample depth, for sampling
stencil a sampler view format with only stencil is required.
Also while here fix up stencil sampling for other formats as well, though
this isn't supported by mesa (ARB_stencil_texturing), and while blits would
use it they don't work neither since they'd also need stencil export.

gallivm: Eliminate 8.8 fixed point intermediates from AoS sampling path.

This change was meant as a stepping stone to use PMADDUBSW SSSE3

speedup on texture intensive shaders (e.g, Google Earth's ocean water

same results, whereas PMADDUBSW only gave an extra 5%, at the expense of
2bits of precision in the interpolation.

I belive that the speedup of this change comes from the reduced register
pressure (as 8.8 fixed point intermediates take twice the space of 8bit
unorm).

Also, not dealing with 8.8 simplifies lp_bld_sample_aos.c code
substantially -- it's no longer necessary to have code duplicated for
low and high register halfs.

Note about lp_build_sample_mipmap(): the path for num_quads > 1 is never
executed (as it is faster on AVX to split the 256bit wide texture
computation into two 128bit chunks, in order to leverage integer
opcodes).  This path might be useful in the future, so in order to

an overflow needs to be the same as with other overflows in the

We would crash when stride was bigger than the size of the buffer.
