Although this could be considered redundant given that the same

mesa: Model INTEL perf query backend after query obj BE

Instead of using the same backend interface as AMD_performance_monitor
this defines a dedicated INTEL_performance_query interface that is
modelled more on the ARB_query_buffer_object interface (considering the
similarity of the extensions) with the addition of vfuncs for
initializing and enumerating query and counter info.

Compared to the previous backend, some notable differences are:

- The backend is free to represent counters using whatever data
  structures are optimal/convenient since queries and counters are
  enumerated via an iterator api instead of declaring them using
  structures directly shared with the frontend.

  This is also done to help us support the full range of data and
  semantic types available with INTEL_performance_query which is awkward
  while using a structure shared with the AMD_performance_monitor
  backend since neither extension's types are a subset of the other.

- The backend must support waiting for a query instead of the frontend
  simply using glFinish().

- Objects go through 'Active' and 'Ready' states consistent with the
  query object backend (hopefully making them more familiar). There is
  no 'Ended' state (which used to show that a query has ended at least
  once for a given object). There is a new 'Used' state, set when a
  query is first begun which implies that we are expecting to get
  results back for the object at some point. There's no equivalent to
  the 'EverBound' state since the spec doesn't require there to be a
  limbo state between generating IDs and associating them with an object
  on query Begin.

The INTEL_performance_query and AMD_performance_monitor extensions are
now completely orthogonal within Mesa main (though a driver could
optionally choose to implement both extensions within a unified backend
if that were convenient for the sake of sharing state/code).

v2: (Samuel Pitoiset)

When looking at the full range matrices, it becomes obvious that the difference
between the standard matrices and the full range matrices is that the full
range matrices are multiplied by 1.164. Together with offsetting the y value
with -16/255, this will scale and offset RGB with the desired quantities.

U and V coefficients are only multiplied with 1.138 to get the full range
matrix. This would actually alter the color somewhat so I figure that's an
error. The full range matrix is consistent with Nvidia's VDPAU implementation.

i965: Enable ARB_transform_feedback2 on Sandybridge.

The only feature over and above ES 3.0 is DrawTransformFeedback().

We already have to do the whole SOL_NUM_PRIMS_WRITTEN counter dance in
order to compute the SVBI value for ResumeTransformFeedback(), at which
point our existing GetTransformFeedbackVertexCount() implementation will
do the trick (though with a stall to CPU map the buffer).

Someday, we could probably implement DrawTransformFeedback() more
efficiently, using the "Load Internal Vertex Count" feature of
3DSTATE_SVB_INDEX and the 3DPRIMITIVE indirect vertex count bit.

Rumor has it this allows people to use WebGL 2.0 on Sandybridge.

Note that we don't need pipelined register writes like Gen7+ because
we use the 3DSTATE_SVB_INDEX command rather than MI_LOAD_REGISTER_MEM.

GLES 3.0 test.  When resuming the transform feedback object, we need to
reset the SVBI counters so we continue writing at the correct point in
the buffer.

Instead of SO_WRITE_OFFSET counters (with a DWord offset), we have the
Streamed Vertex Buffer Index (SVBI) counters, which contain a count of
vertices emitted.

Unfortunately, there's no straightforward way to store the current SVBI
counter values to a buffer.  They're not available in a register.  You
can use a bit in the 3DSTATE_SVB_INDEX packet to copy them to another
internal counter which 3DPRIMITIVE can use...but there's no good way to
extract that either.

So, once again, we use SO_NUM_PRIMS_WRITTEN to calculate the vertex
numbers.  Thankfully, we can reuse most of the existing Gen7+ code.
