v3d: handle debug options with debug_named_value

Switch from using debug_control structure to debug_named_value
structure.

The main nice feature is that it provides a "help" option, so using
"V3D_DEBUG=help" will print all the debug options with a brief

targets/graw-xlib: Add missing dep_x11

glsl: relax rule on varying matching for shaders older than 4.20

This expands on commit c54c42321ea5. See the code comment for full
justifications. At the time of the previous commit Ian wanted to
limit the relaxing of the rule to GLSL 3.30 as that was the highest
version of shaders seen in the wild that were having trouble with
the stricter rules.

However since then I've found that the long standing issue with tess
shaders failing to compile in the game 'Layers Of Fear' is due to
this same issue. The game uses 4.10 shaders and also makes use of
explicit varying locations, so here we relax the rule to 4.20 and
make sure to apply the restriction to shaders using varyings with
explicit locations also.

egl: add support for EGL_EXT_device_drm_render_node

This new EGL extension has been introduced in [1].

When we have a DRM device and a render node, we can advertise the
extension and return the render node name for the
EGL_DRM_RENDER_NODE_FILE_EXT query.

For the special software EGL device, we can advertise the extension
and return NULL for the EGL_DRM_RENDER_NODE_FILE_EXT query, because
we can guarantee that llvmpipe will never use a render node for
rendering operations.

However, llvmpipe might be using a primary node when used with the
GBM platform. So we can't advertise EXT_device_drm in this case.

When we have a DRM device but no render node, that means we're on a
split render/display SoC. We _should_ return the render node used
by the renderonly driver, however Mesa needs more plumbing to allow
this, so let's just disable the extension for now.

llvmpipe: always use draw_regions intersection

This was still used in the linear branch, since it works all a little
differently there (in particular, when using guard band we have to
intersect the draw regions with the viewport, since draw won't clip
for us). However, we should always intersect with draw_regions
(regardless if that includes the intersection with vp or not), since
the viewport can be larger than the fb size, and we don't want to
draw outside the fb (usually harmless, but important for occlusion
queries and shader image/buffer writes).

This fixes various dEQP-GLES31.functional.fbo.no_attachments failures
(which uses oversized viewport with occlusion queries).
The other ci changes aren't really bugs (the humus/Portals image
looks the same, we cannot expect bit-identical results, and
for the piglit quad-invariance test, I think we merely passed it
by accident since our interpolation may give different results
depending on where on the screen a tri is regardless of linear
rasterizer).

llvmpipe: Add a linear rasterizer optimized for 2D rendering.

This change adds:

- an alternative rasterizer, which rasterizes bins in a left->right &
  top->bottom linear fashion;

- triangle -> rectangle detection;

- 1:1 blit detection;

- a special TGSI -> LLVM IR code generation that uses 8-bit SSE integers
  in AoS fashion (as opposed to 32bits floats.)

Altogether these changes yield a 2x to 3x performance improvement for 2D
workloads.  It was designed to render Windows 7 Aero and other Windows
built-in 3D applications (like Windows Media Player, Internet Explorer
11, UWP applications) with minimum CPU utilization, but it should be
generally applicable to other 2D-on-3D applications, like desktop
compositors, HTML browsers, 3D based UI toolkits, etc.

This was mostly the brainchild of Keith Whitwell back in 2010.  I wrote
TGSI -> AoS translation.  And many others added bug-fixes and
enhancements over the years: Roland Scheidegger, Brian Paul, and James
Benton.

Known issues:

- piglit spec@!opengl 1.1@quad-invariance will warn that "left and right
half should match" due to rounding error difference

- These optimized paths to kick in is that depth-buffer must not be
used, so some applications which want to benefit from these improvements
might need to be modified to ensure they use painter's algorithm instead
of depth-buffers.

nir/gcm: be less destructive with instruction order

This changes the pass to extract pinned instructions and not just unpinned
instructions when rescheduling instructions. This stops pinned instructions
from being bunched together when instructions are reinserted into the blocks
which can result in regressions with regards to cycles and instruction
counts on i965 and register use/Max Waves on AMD hardware.

In order to do this we also throw away the post-order depth-first
search linearization algorithm used to re-insert the instructions, which
itself causes possible regressions when instructions are reinserted into
a less than ideal new order (of which the bunched together pinned
instructions is one example). Instead we simply insert instructions in the
reverse order they were extracted. This will simply place instructions
that were scheduled earlier onto the end of their new block and
instructions that were scheduled later to the start of their new block.
With this everything should remain in order without the need to run
over uses.

egl/wayland: Allow EGLSurface to outlive wl_egl_window

According to the EGL spec, it is entirely valid for an EGLSurface to
outlive the native_window it was created from, provided that SwapBuffers
and MakeCurrent return EGL_BAD_NATIVE_WINDOW.

Semantically, -1 means "Unknown; don't validate" but it's really only

need that flexibility for image intrinsics but this makes it more
