I couldn't find this in a spec but the builtin-gl-sample-mask piglit
seems to expect writing to the output sample mask to do nothing when
max num samples == 0.
The ForcedSampleCount property should make everything appear as if
MSAA is disabled. However, it's undefined behavior if depth is
bound, so in that case, we can at least use a lowering pass to
make things *look* like MSAA is off, unless you use atomics to
count invocations.

D3D doesn't have an intrinsic for loading the current sample's
position, only for loading a specific sample's intrinsic. Fortunately,
we can also just get the current sample. So do that.

DXIL adds this in SM6.6, so when we get around to being able to
emit SM6.6, we can conditionally turn this off and support emitting
the new intrinsic. Until then, this is easy.

This *almost* matches what GLSL wants, except for the handling of
large widths. You can see this in the lowering algorithm:
(('bitfield_insert', 'base', 'insert', 'offset', 'bits'),
('bcsel', ('ult', 31, 'bits'), 'insert',
('bfi', ('bfm', 'bits', 'offset'), 'insert', 'base')),
'options->lower_bitfield_insert'),
DXIL's 'bfi' instruction is an inseparable pairing of NIR's 'bfi(bfm(...), ...)',
so we just apply the additional bcsel in the backend.

Note that GL requires input coverage for sample execution mode to
be only the single bit corresponding to the executing sample, so
rearrange things to understand during shader emitting if we're
executing per-sample to emit the right coverage value.

The first container stage ("build") is for dependencies of the build.
These are infrequently-changing things like Visual Studio, LLVM, git,
and also meson. The second container stage ("test") currently depends
on the first, and adds test dependencies like piglit.
This lets us rev piglit without having to rebuild LLVM.

This was copied from the blob before we understood what it did, and it
has questionable utility: there's nothing in the GL, Vulkan, or D3D11
specs that require the result be clamped to the underlying range to
account for imprecision. And it doesn't make sense at all for cubic
filtering, because the result can legitimately be outside the range in
some scenarios. Just remove it.
This fixes a bunch of tests added in vulkan CTS 1.2.8 to test blitting
from compressed textures, which use random inputs and therefore are more
likely to hit the out-of-range condition. For example,
dEQP-VK.api.copy_and_blit.core.blit_image.all_formats.color.2d.etc2_r8g8b8a8_unorm_block.r8g8b8a8_snorm.general_general_cubic.

This appears to do the same thing as CLAMPENABLE on a3xx. That is, it
clamps the result to [0, 1] for unorm formats and [-1, 1] for snorm
formats *after* filtering. In particular it's now more easily observable
with cubic filtering, because cubic filtering can produce values outside
the original range. Presumably this only matters with linear filtering
due to rounding errors when computing the weighted average.

Here are two facts, each mildly unpleasant, quite nasty taken together:
- xcb_wait_for_special_event retries its poll() if the fd woke up but
no matching event arrived, without verifying that the special event
queue is still registered.
- Present gives no in-band notification of window destruction.
Now if the window is destroyed before the swapchain we're in trouble.
Our WSI thread might be stuck in xcb_wait_for_special_event as we're
awaiting a completion that won't come (the pixmap was being presented as
the window, and then the window was destroyed, so no more events can
happen on that window).
The solution is to use xcb_poll_for_special_event, which is
non-blocking, and handle the appropriate edge cases. If we've run the
event queue but we still don't have an image to acquire, we poke the X
server with a request that gently verifies that the window exists,
allowing the thread to exit gracefully in the above case. We detect
when we're busy-looping, and poll on the X connection for up to 1ms in
response to avoid burning the CPU.

From VkPhysicalDeviceLimits [1]:
> maxVertexInputAttributeOffset is the maximum vertex input attribute
offset that can be added to the vertex input binding stride. The offset
member of the VkVertexInputAttributeDescription structure must be
less than or equal to this limit.
The maxVertexInputAttributeOffset is a limit on the offset of a vertex
attribute within a vertex rather than a limit on offsets for vertex
buffer bindings. The code to bind temporary buffers can be removed.
