If nir_opt_vectorize_io isn't called, 16-bit IO is broken.
This is a workaround to keep RADV working and consume incorrect NIR
while other drivers consume correct NIR.
Hopefully this will be removed ASAP.

We will use it to skip lowering mediump IO to 16 bits if the previous
shader has XFB and mediump XFB doesn't work.
Drivers can decide not to lower mediump IO to 16 bits if nir->xfb_info
!= NULL for the pre-rast stage and if nir->info.prev_stage_has_xfb is
true for the FS stage. That way, drivers can lower mediump to 16 bits
for all cases except XFB.

Hopefully this doesn't break it (we may even lack tests), but we need to
know in prelink_lowering whether XFB is enabled or not.
The next commit that adds shader_info::prev_stage_uses_xfb depends on this.

NIR represents low bits of 16-bit IO as a separate vec4, and high bits as
another separate vec4. There is no representation that allows vec8.

When lowering mediump to 16 bits, this will allow drivers to enable
the lowering only for certain pairs of stages, e.g. a driver can lower
mediump for VS->FS, but not GS->FS.
This could also be useful for other things.

Eases NIR maintenance since adding new members no longer requires touching rusticl.
The one const `nir_remove_dead_variables_options` has been duplicated as two local variables because
`default()` cannot be called from const contexts, yet.

Oops. We were being a bit too extensive with our rules and also skipping
the container stage for user (non-marge) pipelines in MRs unless
image-tags.yml had changed. We can't actually do this, because we might
still need to run the jobs to copy the containers into the user's
namespace, even if we don't need to rebuild them.

Do not perform a queue family ownership transfer during memory barriers
if srcQueueFamilyIndex equals dstQueueFamilyIndex, as the Vulkan spec
mandates that this should only happen if the two values are unequal.

Don't report compressed memory type in the case of Xe2 modifiers
as the Vulkan spec requires identical memory types behind the
VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT.
Instead, we require dedicated allocation to get the right
compressed memory in allocation stage. The BMG modifier also
requires scanout flag to set. Refer to comments.

When aux has to be disabled (ISL_SURF_USAGE_DISABLE_AUX_BIT)
for some reasons like VK_SHARING_MODE_CONCURRENT, we simply
cannot implicitly choose any modifier with compression.
Otherwise, we run into a situation that an image is created
with a modifier but without the aux support that modifier
requires. It will fail a CTS test once Xe2 modifiers are
enabled:
dEQP-VK.wsi.wayland.swapchain.private_data.image_sharing_mode
MESA: warning: ../src/intel/vulkan/anv_image.c:1198: image with
modifier unexpectedly has wrong aux usage (VK_ERROR_UNKNOWN)
GFX12.x (MTL) does not show this failure because only one queue
family is present. But they will face the same issue when aux is
disabled for any other reasons:
NotSupported (Only 1 queue families available for
VK_SHARING_MODE_CONCURRENT at vktWsiSwapchainTests.cpp:715)
