docs: Update features.txt and relnotes for GL_ARB_transform_feedback2

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.

i965: Properly reset SVBI counters on ResumeTransformFeedback().

This fixes Piglit's ARB_transform_feedback2/change-objects-while-paused
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.

winsys/amdgpu: reduce max_alloc_size based on GTT limits

Allocating huge buffers in VRAM is not a problem, but when those buffers
start being migrated, the kernel runs into errors because it cannot split
those buffer up for moving through GTT.

gallivm: Override getHostCPUName() "generic" w/ "pwr8" (v4)

If llvm::sys::getHostCPUName() returns "generic", override
it with "pwr8" (on PPC64LE).

This is a work-around for a bug in LLVM: a table entry for "POWER8NVL"
is missing, resulting in (big-endian) "generic" being returned on
little-endian Power8NVL systems.  The result is that code that
attempts to load the least significant 32 bits of a 64-bit quantity in
memory loads the wrong half.

This omission should be fixed in the next version of LLVM (4.0),
but this work-around should be left in place in case some
future version of POWER<n> also ends up unrepresented in LLVM's table.

This workaround fixes failures in the Piglit arb_gpu_shader_fp64 conversion
tests on POWER8NVL processors.
