I'm going to want to go looking at it for an integer texture fix.

Otherwise, when you asked for the _BaseFormat of an rb wrapping a
GL_RGB texture, you got GL_RGBA because that's what we were storing
the texture data as.

Most of this function was just calling
intel_renderbuffer_update_wrapper(), which was called immediately
afterwards in the only caller.

A pure swrast-allocated buffer gets an irb of NULL, so we segfaulted
in the clear-accum test. Just look at the swrast renderbuffer pointer
for handling swrast rbs.

This was horribly broken and has cost everyone more time than we were
ever going to save using it. It might have been fixable, but the
problem it was originally trying to solve can be better solved with
-Werror=missing-prototypes and -Werror=implicit-function-declaration.
Also, it was always producing a big scary warning about how the link
test was non-portable.

Substantially increases performance in GLBenchmark PRO:
- 320x240 => 3.28x
- 1920x1080 => 1.47x
- 2560x1440 => 1.27x
The LD message ignores the sampler unit index and SAMPLER_STATE pointer,
instead relying on hard-wired default state. Thus, there's no need to
worry about running out of sampler units or providing SAMPLER_STATE;
this small patch should be all that's required.
NOTE: This is a candidate for release branches.
(It requires the preceding commit to compile.)

brw_SAMPLE is full of complex workarounds for original Broadwater
hardware, and I'd rather avoid all that for my next Ivybridge patch.

Previously, max_vs_entries was set to 128 for GT1, and 256 for GT2,
based on the PRM (see Vol2, part1, p28). However, Bspec section 1.6.5
indicates that the maximum number of VS entries is 256 for GT1.
No piglit regressions on GT1.

When storing data in a buffer of type DYNAMIC_DRAW, we don't create a
drm_intel_bo for it; instead we store the data in system memory and
defer allocation of the GPU buffer until it is needed. Therefore, in
brw_update_sol_surface(), we can't just consult the "buffer" field of
the intel_buffer_object structure; we need to call
intel_bufferobj_buffer() to ensure that the deferred allocation
occurs.
This parallels a similar fix for gen7 (see commit ba6f4c9).
Fixes piglit test EXT_transform_feedback/buffer-usage on gen6.
This is a candidate for the 8.0 release branch.

This code is unprepared for handling integer (particularly, the
baseFormat of the TexFormat comes out as GL_RGBA, not GL_RGBA_INTEGER,
so the direct call of Driver.ReadPixels crashes due to the int vs
non-int error checking not having happened). I'm frankly tempted to
convert this code to MapRenderbuffer/MapTexImage rather than doing it
as meta ops, now that we have that support.
Improves the remaining crash in Intel oglconform for int-textures to
just a rendering failure.
NOTE: This is a candidate for the 8.0 branch.

This doesn't result in correct rendering -- GL requires that logic ops
work, while the hardware specs say it doesn't do them. I'm not sure
how we would want to handle this.
