We take a slight liberty here by allowing 0 to mean either MAILBOX or
IMMEDIATE, since Wayland (at least) doesn't have a true IMMEDIATE mode
at least MAILBOX won't throttle to vblank.
This only correctly handles intervals of 0 or 1 at the moment.

If the window is destroyed from underneath us while we happen to be in
xcb_wait_for_special_event, there's no recovery. The special event will
never match because the XID is no longer valid, and Present doesn't have
an in-band DestroyNotify. We're going to work around this by using the
poll API instead. If we get an event we short-circuit back to the top of
the "wait for available image" loop, so we drain the whole special event
queue before any other logic. Which means if we run out of special
events (and the connection and swapchain are still valid) that we
_don't_ have enough images available, so to hurry along any events that
the X server hasn't flushed out yet we call GetGeometry on the
swapchain's window. As a side effect this verifies that the window is
still alive.

This test can intentionally make the alloc callback to return NULL, so
we have to handle object creation failures properly. The driver should
also avoid memleaks because the test checks that.

Valhall introduces hardware-allocated varyings. Instead of allocating varying
descriptors on the CPU with a slot based interface, the driver just tells the
hardware how many bytes to allocate per vertex and loads/stores with byte
offsets. This is much nicer!
However, this requires us to rework our linking code to account for separable
shaders. With separable shaders, we can't rely on driver_location matching
between stages, and unlike on Midgard, we can't resolve the differences with
curated command stream descriptors. However, we *can* rely on slots matching. So
we should "just" determine the byte offsets based on the slot, and then
separable shaders work.
For GLES, it really is that easy.
For desktop GL, it's not -- desktop GL brings unpredictable extra varyings like
COL1 and TEX2. Allocating space for all of these unconditionally would hamper
performance. To cope, we key fragment shaders to the set of non-GLES varyings
written by the linked vertex shader. Then we may define an efficient ABI, where
only apps only pay for what they use.
Fixes various tests in dEQP-GLES31.functional.separate_shader.random.* on
Valhall.

Packed TLS has cache-locality benefits on Valhall, compared to Bifrost's flat
TLS. Valhall does support flat TLS, but requires extra arithmetic in the shader
for correct results. At least until we get to generic pointers (and maybe even
then), we can use packed TLS. So just use packed TLS always for proper spilling.

The set of blend shaders is closed. They are completely internal. As such, we
know that the registers we reserve for them suffice, and we don't permit
register spilling. Refusing to support spilling in blend shaders simplifies a
number of parts of the compiler. Add a check that we don't try to spill anyway,
which will silently fail.

Fixes failures on tests like this when the on-disk-cache is enabled:
dEQP-VK.binding_model.descriptor_copy.compute.uniform_buffer_0
We only found them when running full CTS runs. What happens is that we
got a hit from the on-disk shader cache, for several tests using the
same shaders. But some tests seems to be using a uniform buffer, and
others a inline buffer. Right now inline buffers leads to some changes
on the final nir shader, and generated assembly, compared with uniform
buffers. So we got a wrong shader. Fortunately we only got an assert
instead of weird behaviour.
With this commit we include the pipeline layout on the pipeline sha1,
so those two cases would get different sha1. FWIW, this is what other
drivers are already doing.
Surprisingly that didn't cause a problem before.

that entry. And that should only happens if we didn't find the entry
