In commit 7428e6f86a we switched the barrier SEND message's
destination type to UW to avoid problems in SIMD16 compute shaders.
Tessellation control shaders also use barriers, and in vec4 mode, we
were emitting them in align16 mode. The simulator warns that only UD,
D, F, and DF are valid destination types - UW is technically illegal.
So, switch to align1 mode. Either mode should work fine.

This fixes glxgears rendering, which had surprisingly been broken since
late October! Specifically, commit 91d61fbf7c.
glxgears uses glShadeModel(GL_FLAT) when drawing the main portion of the
gears, then uses glShadeModel(GL_SMOOTH) for drawing the Gouraud-shaded
inner portion of the gears. This results in the same fragment program
having two different state-dependent interpolation maps: one where
gl_Color is flat, and another where it's smooth.
The problem is that there's only one gen4_fragment_program, so it can't
store both. Each FS compile would trash the last one. But, the FS
compiles are cached, so the first one would store FLAT, and the second
would see a matching program in the cache and never bother to compile
one with SMOOTH. (Clearing the program cache on every draw made it
render correctly.)
Instead, move it to brw_wm_prog_data, where we can keep a copy for
every specialization of the program. The only downside is bloating
the structure a bit, but we can tighten that up a bit if we need to.
This also lets us kill gen4_fragment_program entirely!

The Vulkan rules for point size are a bit whacky. If you only have a
vertex shader and you use points, then you must write PointSize in your
vertex shader. If you have a geometry or tessellation shader, then it's
dependent on the shaderTessellationAndGeometryPointSize device feature.
From the Vulkan 1.0.38 specification:
"shaderTessellationAndGeometryPointSize indicates whether the
PointSize built-in decoration is available in the tessellation
control, tessellation evaluation, and geometry shader stages. If this
feature is not enabled, members decorated with the PointSize built-in
decoration must not be read from or written to and all points written
from a tessellation or geometry shader will have a size of 1.0. This
also indicates whether shader modules can declare the
TessellationPointSize capability for tessellation control and
evaluation shaders, or if the shader modules can declare the
GeometryPointSize capability for geometry shaders. An implementation
supporting this feature must also support one or both of the
tessellationShader or geometryShader features."
In other words, if the feature is disbled (the client can disable
features!) then they don't write PointSize and we provide a 1.0 default
but if the feature is enabled, they do write PointSize and we use the
one they wrote in the shader. There are at least two valid ways we can
implement this:
1) Track whether or not shaderTessellationAndGeometryPointSize is
enabled and set the 3DSTATE_SF bits based on that and what stages
are enabled, ignoring the shader source.
2) Just look at the last geometry stage VUE map and see if they wrote
PointSize and set the 3DSTATE_SF accordingly.
The second solution is the easiest and the most robust against invalid
usage of the Vulkan API, so we choose to go with that one.
This fixes all of the dEQP-VK.tessellation.primitive_discard.*point_mode
tests. The tests are also broken because they unconditionally enable
shaderTessellationAndGeometryPointSize if it's supported by the
implementation and then don't write PointSize in the evaluation shader.
However, since this is the "robust against invalid API usage" solution,
the tests happily pass. :-)

same bug as R32G32_FLOAT. Applying the same workarounds should be
viable - apparently the R32G32_FLOAT_LD format shouldn't corrupt
integer data which is NaN or other sketchy floating point values.
One irritating caveat is that, because it's a FLOAT format, the
alpha channel or any set to SCS_ONE return 0x3f8 (1.0) rather than
integer 1. So we need shader code to whack those channels to 1.

Applications may query the back buffer age to efficiently perform
partial updates. Generally the application will keep a fixed length
damage history, and use this to calculate what needs to be redrawn
based on the age of the back buffer it's about to render to.
If presented with a buffer that has an age greater than the
length of the damage history, the application will likely have
to completely repaint the buffer.
Our current buffer selection strategy is to pick the first available
buffer without considering its age. If an application frequently
manages to fit within two buffers but occasionally requires a third,
this extra buffer will almost always be old enough to fall outside
of a reasonably long damage history, and require a full repaint.
This patch changes the buffer selection behaviour to prefer the oldest
available buffer.
By selecting the oldest available buffer, the application will likely
always be able to use its damage history, at a cost of having to
perform slightly more work every frame. This is an improvement if
the cost of a full repaint is heavy, and the surface damage between
frames is relatively small.
It should be noted that since we don't currently trim our queue in
any way, an application that briefly needs a large number of buffers
will continue to receive older buffers than it would if it only ever
needed two buffers.

When EGL is used on some other thread than the thread that drives the
main wl_display queue, the Wayland EGL dri2 implementation is
vulnerable to a race condition related to display round trips and global
object advertisements.
The race that may happen is that after after a proxy is created, but
before the queue is set, events meant to be emitted via the yet to be
set queue may already have been queued on the wrong queue.
In order to make it possible to avoid this race, wayland 1.11
introduced new API that allows creating a proxy wrapper that may be used
as the factory proxy when creating new proxies via Wayland requests. The
queue of a proxy wrapper can be changed without effecting what queue
events emitted by the actual proxy will be queued on, while still
effecting what default queue proxies created from it will have.
By introducing a wl_display proxy wrapper and using this when performing
round trips (via wl_display_sync()) and retrieving the global objects (via
wl_display_get_registry()), the mentioned race condition is avoided.
