Include Panfrost's gitlab.ci.yml file from Mesa's main .gitlab-ci.yml so
we test on devices with Panfrost.
This uses LAVA to schedule jobs in the devices and will be the base for
testing Etnaviv, Lima, etc.

This is a port of Nanley's 904c2a617d
from i965 to iris.
One concern is that iris uses larger batches, and also emits far fewer
commands, so we may come closer to the 500 limit within a batch, and
could need to supplement this with actual counting. Manhattan 3.0 had
239 3DSTATE_CONSTANT_PS packets in a batch, Unigine Valley had 155.
So it seems like we're still in the realm of safety.
Just following the spec. Somewhat unclear whether this applies to NULL

It appears we never had a test in piglit or deqp sampling from a null
surface...
It turns out this triggers a hang on IVB only. Updating the null
surface format to R32_UINT fixes the hang on ivb and doesn't affect
other platforms, so set it by default for all platforms.

We were supplying __DRI2_THROTTLE_SWAPBUFFER, rather than the obvious
choice of __DRI2_THROTTLE_COPYSUBBUFFER. This meant that we hit the
swap-based frame throttling. glXCopySubBuffer doesn't seem like it's
intended to be a frame boundary, so we'd like to avoid this throttling.

glXCopySubBufferMESA copies data from the back buffer to the front,
so it needs to perform a MSAA downsampling operation just like
glXSwapBuffers would.
Currently, the CopySubBuffer implementations supply a throttle reason
of __DRI2_THROTTLE_SWAPBUFFERS, so they hit this path and work today.
But we'd like to avoid swapbuffer throttling in this case, so the next
patch will change that reason.

Callers should have liveness info ready. Ideally we'd have a nice

There are unfortunately two distinct liveness analysis passes in the
compiler right now -- one good (but complex) pass used by RA based on
solving data flow equations, and one awful (but simple) pass used for
dead code elimination and bundling based on an abstract walk of the AST.
