useful for nir-based gallium meta, we have a tgsi equivalent already.

When given (e.g.) 3x 16-bit components to store on a device that
isn't using native 16-bit loads and stores, we should be lowering
that into one 32-bit store and one masked store. Instead, the logic
here ends up returning that the best we can do is one 8-byte store,
which is clearly wrong. Stores should round down, loads should
round up.

Those are not reused, so this will be the first and only allocation, so
no need to use the "realloc" variants.
For the fs_reg arrays, there's currently no particular reason to keep
them uninitialized, so zero-initialize them too -- not ideal but better
than random values.

GFX10.3 doesn't natively support mesh/task shader invocations query
and they need to be emulated in shaders. In order to share more code
between GFX10.3 and GFX11, it's easier to use the same size as GFX11.

GFX11 uses pipeline statistics for mesh/task queries but on GFX10.3
they need to be emulated. Though the number of mesh/task shader
invocations would be copied to the pipeline statistics range to
simplify the implementation.

We now have a lot of feature toggles in fd_dev_info. Generate
env var options for all of them to quickly test whether feature
misbehaves or test its impact on the performance.
FD_DEV_FEATURES=%feature_name%=%value%:%feature_name%=%value%:...
e.g.
FD_DEV_FEATURES=has_fs_tex_prefetch=0:max_sets=4

After introduction of A7XX it doesn't make sense to define base GPU
properties in A6xxGPUInfo. Now we move to a more clean definition:
- a6xx_base + a6xx_genX - for A6XX
- a7xx_base + a7xx_xxx - for A7XX, there is no sub-gens clearly
identifiable at the moment.

This is based off the original GLSL IR pass but it is much much
simpler as it doesn't need to do all of the hackery required in
GLSL IR to achieve the lowering.

This reworks the intel_compute_pixel_hash_table_nway() pixel pipe
hashing table computation helper to handle cases where some pixel
pipes have processing power different from the others, this is helpful
for Gfx12.7+ platforms where there are pixel pipes with 1 DSS as well
as pixel pipes with 2 DSSes, which currently can lead to a serious
performance bottleneck in the pixel pipes with lower processing power.
In order to avoid such a load imbalance the
intel_compute_pixel_hash_table_nway() function will now take two pixel
pipe bitsets instead of one: Pixel pipes enabled on both bitsets will
appear with twice the frequency on the table as pixel pipes which only
appear on one bitset. See the comments below for more details on the
algorithm used to construct a pixel hashing table with the desired
properties.
With this change rendering performance improves by about 25% on a
fused MTL platform -- The list of specific configs this is expected to
show an improvement on is not included here since the list is rather
long and some of the configs may still be embargoed or may never be
productized, but in order to find out whether your Gfx12.7+ device
could be affected by this you can check the output of the
intel_dev_info tool from the Mesa tree and see if there are multiple
"pixel pipe" entries with different DSS count. That isn't expected to
occur on any DG2 configuration, only on MTL+ platforms, so this change
should have no effect at all on DG2 (it's easy to convince oneself
that it won't since for DG2 mask1 should equal mask2 so mask2 will be
set to zero at the beginning of intel_compute_pixel_hash_table_nway()
and the new swzx[] permutation will be set to the identity).

They're now printed as part of the op for textures and we've changed the
names to follow the PTX convention. For buffers and cube maps, I had to
come up with my own thing but I think the result is okay.
