We need to add a new bit since the GL ES exts require functionality from
a combination of texture buffer extensions as well as images (for
imageBuffer) support. Additionally, not all GPUs support all the texture
buffer functionality (e.g. rgb32 isn't supported by nv50).

This fixes all failures with dEQP tests in this area. While
ARB_texture_buffer_object explicitly says that GetTexLevelParameter & co
should not be supported, GL 3.1 reverses this decision and allows all of
these queries there.
Conversely, there is no text that forbids the buffer-specific queries
from being used with non-buffer images.

Apparently, BLORP has always set these bits unconditionally.
However, setting them unconditionally appears to regress tests using
texture projection, 3D samplers, integer formats, and vertex shaders,
all in combination, such as:
functional.shaders.texture_functions.textureprojlod.isampler3d_vertex
Setting them on Gen4-5 appears to regress Piglit's
tests/spec/arb_sampler_objects/framebufferblit.
Honestly, it looks like the real problem here is a lack of precision.
I'm just hacking around problems here (as embarassing as it is).

When using seamless cube map mode and NEAREST filtering, we explicitly
overrode the wrap modes to CLAMP_TO_EDGE. This was to implement the
following spec text:
"If NEAREST filtering is done within a miplevel, always apply apply
wrap mode CLAMP_TO_EDGE."
However, textureGather() ignores the sampler's filtering mode, and
instead returns the four pixels that would be blended by LINEAR
filtering. This implies that we should do proper seamless filtering,
and include pixels from adjacent cube faces.
It turns out that we can simply delete the NEAREST -> CLAMP_TO_EDGE
overrides. Normal cube map sampling works by first selecting the
face, and then nearest filtering fetches the closest texel. If the
nearest texel was on a different face, then that face would have been
chosen. So it should always be within the face anyway, which
effectively performs CLAMP_TO_EDGE.

Our driver uses the brw_render_cache mechanism to track buffers we've
rendered to and are about to sample from.
Previously, we did a single PIPE_CONTROL with the following bits set:
- Render Target Flush
- Depth Cache Flush
- Texture Cache Invalidate
- VF Cache Invalidate
- Instruction Cache Invalidate
- CS Stall
This combined both "top of pipe" invalidations and "bottom of pipe"
flushes, which isn't how the hardware is intended to be programmed.
The "top of pipe" invalidations may happen right away, without any
guarantees that rendering using those caches has completed. That
rendering may continue altering the caches. The "bottom of pipe"
flushes do wait for the rendering to complete. The CS stall also
prevents further work from happening until data is flushed out.
What we wanted to do was wait for rendering complete, flush the new
data out of the render and depth caches, wait, then invalidate any
stale data in read-only caches. We can accomplish this by doing the
"bottom of pipe" flushes with a CS stall, then the "top of pipe"
flushes as a second PIPE_CONTROL. The flushes will wait until the
rendering is complete, and the CS stall will prevent the second
PIPE_CONTROL with the invalidations from executing until the first
is done.
Fixes dEQP-GLES3.functional.texture.specification.teximage2d_pbo
subtests on Braswell and Skylake. These tests hit the meta PBO
texture upload path, which binds the PBO as a texture and samples
from it, while rendering to the destination texture. The tests
then sample from the texture.
For now, we leave Gen4-5 alone. It probably needs work too, but
apparently it hasn't even been setting the (G45+) TC invalidation
bit at all...

dEQP-GLES31.functional.fbo.no_attachments.* draws a quad with no
framebuffer attachments, using a shader that discards based on
gl_FragCoord. It uses occlusion queries to inspect whether pixels
are rendered or not.
Unfortunately, the hardware is not dispatching any pixel shaders,
so discards never happen, and the full quad of pixels increments
PS_DEPTH_COUNT, making the occlusion query results bogus.
To understand why, we have to delve into the WM_INT internal
signalling mechanism's formulas.
The "WM_INT::Pixel Shader Kill Pixel" signal is defined as:
3DSTATE_WM::ForceKillPixel == ON ||
(3DSTATE_WM::ForceKillPixel != Off &&
!WM_INT::WM_HZ_OP &&
3DSTATE_WM::EDSC_Mode != PREPS &&
(WM_INT::Depth Write Enable || WM_INT::Stencil Write Enable) &&
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(3DSTATE_PS_EXTRA::PixelShaderKillsPixels ||
3DSTATE_PS_EXTRA:: oMask Present to RenderTarget ||
3DSTATE_PS_BLEND::AlphaToCoverageEnable ||
3DSTATE_PS_BLEND::AlphaTestEnable ||
3DSTATE_WM_CHROMAKEY::ChromaKeyKillEnable))
Because there is no depth or stencil buffer, writes to those buffers
are disabled. So the highlighted condition is false, making the whole
"Kill Pixel" condition false. This then feeds into the following
"WM_INT::ThreadDispatchEnable" condition:
3DSTATE_WM::ForceThreadDispatch != OFF &&
!WM_INT::WM_HZ_OP &&
3DSTATE_PS_EXTRA::PixelShaderValid &&
(3DSTATE_PS_EXTRA::PixelShaderHasUAV ||
WM_INT::Pixel Shader Kill Pixel ||
WM_INT::RTIndependentRasterizationEnable ||
(!3DSTATE_PS_EXTRA::PixelShaderDoesNotWriteRT &&
3DSTATE_PS_BLEND::HasWriteableRT) ||
(WM_INT::Pixel Shader Computed Depth Mode != PSCDEPTH_OFF &&
(WM_INT::Depth Test Enable || WM_INT::Depth Write Enable)) ||
(3DSTATE_PS_EXTRA::Computed Stencil && WM_INT::Stencil Test Enable) ||
(3DSTATE_WM::EDSC_Mode == 1 && (WM_INT::Depth Test Enable ||
WM_INT::Depth Write Enable ||
WM_INT::Stencil Test Enable)))
Given that there's no depth/stencil testing, no writeable render target,
and the hardware thinks kill pixel doesn't happen, all of these
conditions are false. We have to whack some bit to make PS invocations
happen. There are many options.
Curro suggested using the UAV bit. There's some precedence in doing
that - we set it for fragment shaders that do SSBO/image/atomic writes
when no color buffer writes are enabled. We can simply include discard
here too.

In the first pass of implementing exact handling, I made a mistake with
search-and-replace. In particular, we only reallly handled exact/inexact
on the root of the tree. Instead, we need to check every node in the tree
for an exact/inexact match. As an example of this, consider the following
GLSL code
precise float a = b + c;
if (a < 0) {
do_stuff();
}
In that case, only the add will be declared "exact" and an expression that
looks for "b + c < 0" will still match and replace it with "b < -c" which
may yield different results. The solution is to simply bail if any of the
values are exact when matching an inexact expression.
Found with grep and inspection. Test compiled on RPi hw.

Back in the dawn of time, we used to do immediate uploads for the vertex

vertex data, so we started feeding in a VBO (in all cases). But we
forgot to disable some things that apply in such cases, specifically
primitive restart and index bias. The latter was causing WoW and other
Blizzard games trouble as they use a pattern where they draw with a base
vertex (aka index bias), followed by texture uploads (aka blits,
internally).
