In case the case of kmsro and freedreno driver, freedreno will fail to
with the xmlconfig errors as the kmsro declaration doesn't have defaults
for the freedreno options. Instead of directly using v3d_driconf for
kmsro, add native kmsro_driconf, which optionally includes v3d and
freedreno options.

The kmsro (in theory) can be using any other driver. In order to
simplify handling of driver public headers, move kmsro definition to the
bottom of the drm_helper.h

In 9ffd00bcf1 ("nir_to_tgsi: Pack our tex coords into vec4
nir_tex_src_backend[12]"), Emma added a pair of back-end sources to
nir_tex_instr to allow complex lowering to be done in NIR. This adds a
tiny bit more hw-specific back-end information that a NIR lowering pass
can communicate to the back-end compiler.
While the opcode contains most of the information needed, some thing
such as the presence of offsets is currently only communicated via the
presence of specific source types in the source list. This information
is gone when the texture instruction is lowered to back-end sources.
Adding a backend_flags field fixes this by allowing the lowering pass to
communicate a small amount of side-band information if needed.

Currently we don't properly support using he two IDX registers in the
same ALU CF, so work around this by enforcing a new CF if both indices
are used.

Our implementation only preserves the provoking vertex if it is last,
and always preserving it would be more draw-time validation because the
vertex ordering is tied up with the tessellation domain origin. It turns
out we didn't notice this because the tests aren't good enough to catch
the issue.

`rules:changes:compare_to` resolved firstly pushed branch pipelines,
which always evaluated `rules:changes` as true which breaks the workflow
Since we now explicitely say, that we compare against `main` repository,
GitLab can evaluate against real changes.

Add helper functions vk_memory_to_image_copy_layout() and
vk_image_to_memory_copy_layout(), which will be useful in
VK_EXT_host_image_copy implementations.
vk_memory_to_image_copy_layout() is similar to
vk_image_buffer_copy_layout(), except the second parameter is
VkMemoryToImageCopyEXT instead of VkBufferImageCopy2.

Calling anything after nir_trivialize_registers() risks undoing some of
its work.
In this case, brw_nir_adjust_payload() will do a constant folding pass
if any payload adjusting happened, and that can turn a bunch of
@store_regs into basically noops.

This is a modified version of a commit originally in !7698. This version
add the changes to brw_fs_copy_propagation. If the address passed to
fs_visitor::swizzle_nir_scratch_addr is a constant, that function will
generate SHL with two constant sources.
DG2 uses a different path to generate those addresses, so the constant
folding can't occur there yet. That will be addressed in the next
commit.
What follows is the commit change history from that older MR.
v2: Previously this commit was after `intel/fs: Combine constants for
integer instructions too`. However, this commit can create invalid
instructions that are only cleaned up by `intel/fs: Combine constants
for integer instructions too`. That would potentially affect the
shader-db results of each commit, but I did not collect new data for
the reordering.
v3: Fix masking for W/UW and for Q/UQ types. Add an assertion for
!saturate. Both suggested by Ken. Also add an assertion that B/UB types
don't matically come back.
v4: Fix sources count. See also ed3c2f73db ("intel/fs: fixup sources
number from opt_algebraic").
v5: Fix typo in comment added in v3. Noticed by Marcin. Fix a typo in a
comment added when pulling this commit out of !7698. Noticed by Ken.

opt_copy_propagation can create invalid instructions like
shl(8) vgrf96:UD, 2d, 8u
These instructions will be cleaned up by opt_algebraic. The irony is
opt_algebraic converts these to simple mov instructions that
opt_copy_propagation should clean up. I don't think we want a loop like
do {
progress = false;
if (OPT(opt_copy_propagation)) {
OPT(opt_algebraic);
OPT(dead_code_eliminate);
}
} while (progress);
But maybe we do?
Maybe this would be sufficient:
while (OPT(opt_copy_propagation))
OPT(opt_algebraic);
OPT(dead_code_eliminate);
No shader-db or fossil-db changes (yet) on any Intel platform. This is
expected.
v2: Do opt_algebraic immediately after every call to
opt_copy_propagation instead of being clever. Suggested by Lionel.
