When I originally added the FFMA opcode here, I added the FMAD opcode
instead of the FMA opcode. The reason for this is that it works on
32-bit values as well, so that seemed like a better fit.
But that's not correct, as the FMA opcode isn't a fused operation, so
let's correct the opcode.
This isn't currently in use, because we currently lower away all ffma
opcodes on the NIR level, but that's about to change.
While we're at it, let's also update the opcode name to match the DXIL
documentation.

We don't support stencil-exports yet, and even when we will, we might
not support it on all hardware. So we really need an alternative plan
here, even when render_condition_enable is true.
Fixing this properly is much more involved, and depends on reworking
render-condition along the lines that we do in !7746 to support pausing
and resuming properly first. So let's do the minimal thing, which is to
allow this to work in cases where no render-condition is active.

To properly support multi-planar images, we don't want to set metadata
on anything other than the first plane. To achieve this radv currently
checks for the image TILING and assumes LINEAR means it's not the first
plane.
However this doesn't account for images with a single LINEAR plane. We
still want to set metadata on those, e.g. to properly set the scanout
bit in the tiling flags.
Instead of checking for LINEAR, check if the offset is zero. Only the
first plane has a zero offset on AMD.
This mirrors the radeonsi logic [1].
While at it, move the metadata declaration into the if block.

NTT doesn't handle uniforms, and requires them to have been lowered to
UBOs. But for drivers that don't set
nir_shader_compiler_options::lower_uniforms_to_ubo to true, this won't
have happened yet. Neither Zink nor V3D sets this option, and in the
case of Zink this isn't trivial to change.
So let's lower uniforms to UBOs in this case in NTT instead.

When blitting just the stencil aspect, the source and destination
resources are prepared/setup twice. Move the unconditional resource
setup into the aspect_mask loop to avoid this.
In addition, use the aspect provided by the loop instead of the mask
provided by the info parameter.

The table constructor and the table lookup were doing different things
for big-endian. This fixes MesaFormatsTest.FormatFromFormatAndType and
MesaFormatsTest.FormatMatchesFormatAndType failing to round-trip for
GL_RGBA / GL_SHORT, which we're not currently running in CI for s390x,
but which a subsequent commit will enable.

Compute the number of components of the destination vector from the
bitsize when eg. a 16-bit vec2 vertex fetches is splitted. This is
because the dst will be a v1, so the p_create_vector should be created
from two v2b fro both sizes to match.
This prevents a regression from the next change which will split
typed vertex buffer loads on GFX6 and GFX10+.

There is a path to blit stencil buffers reinterpreting the stencil data
as an RGBA8888 or R8 float texture.
This works fine except for the case when the stencil buffer is
multisampled, and the blit operation needs to resolve it: an average of
the samples is done, which is incorrect, as only one sample must be
used.
This can be observed n the piglit test
`ext_framebuffer_multisample-unaligned-blit 2 stencil downsample -auto
-fbo`, specifically in the triangles border.
To avoid this averaging, let's reinterpret the stencil data as RGBA8888
or R8 uint texture.

Two main reasons:
As described in the previous commit, sending buffers to the Wayland
compositor as quickly as possible effectively results in mailbox
behaviour.
Also, doing the same as for MAILBOX present mode provides the following
benefits:
* We use more images in the swapchain, which avoids stalls on the client
side if the Wayland compositor directly uses the client buffers for
scanout.
* We wait for fences to signal before submitting a new buffer, which
avoids missing frames in the Wayland compositor due to fences not
signalling in time for a flip.

This allows Xwayland to forward buffers to the Wayland compositor ASAP
for fullscreen / undecorated windows, which in turn allows true mailbox
behaviour in the Wayland compositor.
Without this, Xwayland has to emulate the mailbox behaviour itself,
which it cannot do as well as the Wayland compositor by design.
