intel/isl: Use uint64_t for computed byte offsets

This is mostly a bit of future-proofing.  We never end up with offsets
that don't fit in 32 bits today because, thanks to driver limitations
caused by relocations, we don't allocate buffers bigger than 2GB today.
However, if we ever did, it's possible to create a surface on modern
platforms that consumes more than 4GB and we would end up with wrapping
in our offset calculations.

glsl/opt_algebraic: disable invalid optimization

When operators other than eq and ne are involved we can't really
move operands around and negate them because such transformation
may change the value of the whole expression.

Some examples:

For unsigned var:
0 >= 1u + var would eventually become 0xffffffff >= var,
which would always evaluate to true, when original expression
was true only for var == 0xffffffff.

For signed var:
0 >= 1 + var would become -1 >= var, which would evaluate to
false for var == 2147483647, when original expression evaluated
to true (because signed overflow is defined to wrap around in
glsl, 1 + 2147483647 == -2147483648, so 0 >= -2147483648).

panfrost: Rewrite the clear colour packing code

At the beginning of a render pass, the hardware will fill the tilebuffer
with an arbitrary 128-bit word. To implement colour clears, the driver
must pack the API-specific clear colour according to the 128-bit layout
of the tilebuffer. This layout depends only on the render target format.

The existing code to handle this was based on loose guesswork. It works
for the format / clear colour combinations tested in dEQP-GLES3, but it
is severely deficient in the general case.  It works by matching on the
PIPE format of the render target (not the layout of the tilebuffer). For
special cased PIPE formats, it open codes a buggy pack routine.
Otherwise, it defaults to util_pack_color in the hope that will work.
Since util_pack_color doesn't know anything about Mali tilebuffer
layouts, that means it's defaulting to wrong behaviour.

Now that we understand internal tilebuffer layouts, let's rewrite the
packing code. Instead of matching PIPE formats, map the PIPE format to
the internal tilebuffer layout using the common table, ensuring the
mapping remains in sync with the render target descriptor. Then for
blendable tilebuffer formats, pack using a common float -> fixed point
path supporting optional sRGB translation. Raw formats use
util_pack_color as before.

For formats with less than 8 bits per channel, the new code uses the
fractional bits of the fixed-point representation. This is required for
correct dithering if the clear colour is not exactly representable in
the final low precision format.

In summary, at least the following bugs in the old code are fixed:

   * Swapped R/B channels with sRGB
   * Swapped R/B channels with some missing formats
   * Incorrect dithering with RGB565, RGB5_A1

Fixes the following test cases:

   dEQP-EGL.functional.wide_color.window_8888_colorspace_srgb
   dEQP-EGL.functional.wide_color.pbuffer_8888_colorspace_srgb
   dEQP-EGL.functional.wide_color.window_888_colorspace_srgb
   dEQP-EGL.functional.wide_color.pbuffer_888_colorspace_srgb

Later in the series, unit tests are added for the new implementation.

panfrost: Fix leak of render node fd

Transfer ownership of the render node fd to the panfrost_device (minor
change to panvk), and then close the file descriptor for the render node
bound to the panfrost_device when destroying the panfrost_device. Of all
the users of panfrost_open_device, panvk is the only one that correctly
closed the fd before. Accordingly, this fixes an fd leak in the Gallium
driver (and performance counter utilities).

This fix still applies to the Gallium driver when renderonly is in use--
although renderonly closes its own fd, the fd is _duplicated_ in
panfrost_drm_winsys.c, so renderonly and panfrost must _both_ close
their respective fd to fix the leak.

This fixes a crash when running dEQP-EGL for more than two hours.
dEQP-EGL creates a new screen for every test case and then immediately
destroys it. If destroying a screen leaks the fd, this causes the number
of open file descriptors to increase monotonically until the process
ends. This will eventually hit the system limit for number of open files
and abort the process.

This bug was identified while attempting to run the OpenGL ES
conformance tests via cts-runner, and then confirmed with `lsof`. With
the fix, the number of file descriptors reported by `lsof | wc -l` is
now constant while running dEQP-EGL as expected.

vulkan/wsi/wayland: always initialize format vector

In wsi_wl_display_init(), the format vector is initialized only when the
caller sets the function to query the formats/modifiers. But
wsi_wl_display_finish() always release the vector, no matter if it has
been initialized or not.

For now it just works because the u_vector_foreach() macro works when
the format vector is uninitialized, but it is a weird design to try to
release something that has not been initialized.

So in this patch we start to always initialize the format vector, even
when not querying formats/modifiers.

vulkan/wsi/wayland: generalize modifier handling

Instead of having hard-coded lists of modifiers for argb8888 and
xrgb8888, store a list of modifiers alongside each VkFormat. To
achieve this goal, introduce a new struct wsi_wl_format that holds
both a VkFormat and a modifier list, and use it for the items in
the formats list.

This commit unlocks non-{A,X}RGB8888 formats, which were previously
always disabled for linux-dmabuf.

vulkan/wsi/wayland: fold wsi_wl_display_swrast and wsi_wl_display_dmabuf into parent

The two structs wsi_wl_display_swrast and wsi_wl_display_dmabuf have in
common the list of formats and the only difference between both is the
interface object.

As we know that only one of the arrays is populated (we never bind to
wl_shm and the dmabuf interface simultaneously), we can move the members
of these structs to wsi_wl_display and simplify the code.

This is based on previous work of Simon Ser <contact@emersion.fr>.

vulkan/wsi/wayland: fix crash when force_bgra8_unorm_first is true

When force_bgra8_unorm_first is true, we access display->formats and
change the order of certain formats. The final result is BGRA8_UNORM
being the first in the format list, as some clients require this.

But we are trying to do this before before setting up display->formats,
so it should result in a crash. Fix this by changing the order of
things. Now we first set up display->formats before trying to access it.

nir/dead_cf: Do not remove loops with loads that can't be reordered

If a loop is followed by a barrier, the ordering between a load inside
the loop and other memory operations after the barrier may have to be
preserved depending on the type of memory involved.  This is relevant
when the memory is writeable by other invocations.  In such case, it
is not valid to completely eliminate the loop.

This commit doesn't attempt to precisely catch the barrier case, as
analysis could become too complex.  It simply assumes it can't drop
the loops that contain certain types of loads unless those are known
to be safe to reorder (via the access flag).
