Turns out the python scripts are _not_ fully python 3 compatible.
As Ilia reported using get_xmlpool.py with LANG=C produces some weird

Even though the issue was spotted with the autoconf build, it exposes a
genuine problem with the script (and lack of lang handling of the meson

This reverts commit 095515e16c.
This breaks KHR-GL46.map_buffer_alignment.functional on i965.
This code was apparently not reviewed and I don't know why we would
move from a driver configurable constant to a hardcoded value for all
drivers. This really looks like an accidental hack push.
As far as I can tell, no one reviewed these changes, they made i965
assert fail on driver load, and I am not certain they are correct.
(Hopefully reverting these does not break radeonsi too badly...)
The uniform related changes seem fine and reasonable, but the texture
image units change is possibly incorrect. According to the
OES_tessellation_shader spec issue 5:
(5) How are aggregate shader limits computed?
RESOLVED: Following the GL 4.4 model, but we restrict uniform
buffer bindings to 12/stage instead of 14, this results in
MAX_UNIFORM_BUFFER_BINDINGS = 72
This is 12 bindings/stage * 6 shader stages, allowing a static
partitioning of the bindings even though at most 5 stages can
appear in a program object).
MAX_COMBINED_UNIFORM_BLOCKS = 60
This is 12 blocks/stage * 5 stages, since compute shaders can't
be mixed with other stages.
MAX_COMBINED_TEXTURE_IMAGE_UNITS = 96
This is 16 textures/stage * 6 stages.
which definitely is including compute shaders in that last limit.
Not including compute shaders breaks the following test:
dEQP-GLES31.functional.state_query.integer.max_combined_texture_image_units_getinteger
There was enough breakage that I figured we should just send this back
to the drawing board.

These have been removed. Unfortunately auto-upgrade doesn't work for
jit. (Worse, it seems we don't get a compilation error anymore when
compiling the shader, rather llvm will just do a call to a null
function in the jitted shaders making it difficult to detect when
intrinsics vanish.)
Luckily the signed ones are still there, I helped convincing llvm
removing them is a bad idea for now, since while the unsigned ones have
sort of agreed-upon simplest patterns to replace them with, this is not
the case for the signed ones, and they require _significantly_ more
complex patterns - to the point that the recognition is IMHO probably
unlikely to ever work reliably in practice (due to other optimizations
interfering). (Even for the relatively trivial unsigned patterns, llvm
already added test cases where recognition doesn't work, unsaturated
add followed by saturated add may produce atrocious code.)
Nevertheless, it seems there's a serious quest to squash all
cpu-specific intrinsics going on, so I'd expect patches to nuke them as
well to resurface.
Adapt the existing fallback code to match the simple patterns llvm uses
and hope for the best. I've verified with lp_test_blend that it does
produce the expected saturated assembly instructions. Though our
cmp/select build helpers don't use boolean masks, but it doesn't seem
to interfere with llvm's ability to recognize the pattern.

We have to be a bit careful with this one because we want it to run in

Later calls assume that we've lowered away copy_deref instructions and
we don't want to introduce any more.

In spite of the lack of any shader-db improvement, this patch completely
eliminates spilling in the Batman: Arkham City tessellation shaders.
This is because we are now able to detect that the temporary array
created by DXVK for storing TCS inputs is a copy of the input arrays and
use indirect URB reads instead of making a copy of 4.5 KiB of input data
and then indirecting on it with if-ladders.

This peephole optimization looks for a series of load/store_deref or
copy_deref instructions that copy an array from one variable to another
and turns it into a copy_deref that copies the entire array. The
pattern it looks for is extremely specific but it's good enough to pick
up on the input array copies in DXVK and should also be able to pick up
the sequence generated by spirv_to_nir for a OpLoad of a large composite
followed by OpStore. It can always be improved later if needed.

This is unsurprising because nir_lower_vars_to_ssa already effectively
does structure and array splitting internally. It doesn't actually
split the variables but it's ability to reason about aliasing in the
presence of arrays and structures and pick out scalars or vectors to be
lowered to SSA values is fairly advanced.

This pass looks for array variables where at least one level of the
array is never indirected and splits it into multiple smaller variables.
This pass doesn't really do much now because nir_lower_vars_to_ssa can
already see through arrays of arrays and can detect indirects on just
one level or even see that arr[i][0][5] does not alias arr[i][1][j].
This pass exists to help other passes more easily see through arrays of
arrays. If a back-end does implement arrays using scratch or indirects
on registers, having more smaller arrays is likely to have better memory
efficiency.
