The big discovery is the "number of uniform registers" field. I learned
about this one accidentally when my preamble shaders weren't working
right, because we had inadvertently hardcoded "at most 32 registers" :-)
In the course of identifying that field, I found that the pipeline
address is used as a tagged pointer, with some unknown field in the
bottom bits and alignment demanded. The XML is updated to account for
this.
I later found that there's also a "number of general purpose registers
used by the preamble shader" field. I missed this one first, because the
encoding is slightly different from the usual "number of general purpose
registers in the main shader" field. The specification is slightly
coarser. I don't know why the hardware needs that
information anyway -- occupancy of the preamble shader should be
irrelevant -- but it's not a big deal.
Finally I found that the "more than 4 textures?" bit is... not that. I
do not yet know what it is, but it is... not that.
These all use the new groups() modifier for GenXML

The start field in the Uniform USC word is only 8-bits, whereas 9-bits
are required to address the entire uniform register file. This other
word gets used for the high half, with start indexed from u128l in
the natural way.
Apparently spending the evening stuffing too many uniforms into Metal is
paying off.

This gets shader-db's runner working, in conjunction with a shader-db ./run
modified to set ASAHI_MESA_DEBUG=precompile. This flag triggers precompiles of
all shaders witha default key so we can exercise the compiler.

It has not been used in quite some time but adds maintainence burden.
Its function is replaced by drm-shim in conjunction with shader-db's
./run, which goes through the actual driver.

nir_opt_preamble will be crucial to optimize out the lowering for array
textures on AGX, which involves this AGX-specific sysval.

For example if src0 is 0x80000000 we should return 1, not 0.

data->vars->tmax will be overwritten by inner_vars.tmax so we have to
set inner_vars.tmax instead. This probably doesn't affect anything in
practise.

Non-uniform descriptors are not loaded in NIR and instead the pointer is
passed to abi->load_sampler_desc. It can be the case that only the texture
or sampler uses this path.
For the descriptor which doesn't use the path, we would previously pass
NULL to abi->load_sampler_desc.
