C++ requires explicit casts from integers to enums. Fixes errors like
the following when trying to use Asahi GenXML from a GTest unit test.
src/asahi/lib/agx_pack.h:554:23: error: assigning to 'enum agx_channels' from incompatible type 'uint64_t' (aka 'unsigned long long')
values->channels = __gen_unpack_uint(cl, 0, 6);

Required to clamp array indices against the array sizes per the GLSL
spec. Metal also does this, implying it's required by the hardware for
correct operation.

As far as I can tell, these *must* be tiled. Other than that, the

Like explicit LODs, biases must be 16-bit, so add a lowering rule for
this. With the LOD mode selection updated for txb, we can then ingest
biases like explicit LODs and allowlist txb. Passes:
dEQP-GLES2.functional.shaders.texture_functions.fragment.texture2d_bias
dEQP-GLES2.functional.texture.mipmap.2d.bias.*

We still need to implement discard itself, but this means we don't need
to worry about discard_if. This compiles down to the same idiom as
the vendor compiler (Metal) generates

This lets us support indirect access to UBOs easily. The existing
constant special case disappears too, since the peephole optimizer can
inline the constant later. (note: this is too conservative since we can
go up to 16-bit immediates...)
Unfortunately, nir_opt_algebraic can't seem to optimize expressions like
"((a << 3) + 4) >> 2" to "(a << 1) + 1" which would be necessary for
reasonable perf out of this...

Lower to `sample_mask = 0`. Actually that implements a demote... doing
discard correctly probably requires rewriting the shader control flow to
insert a return where necessary...
Also, possibly we should be lowering this in NIR to play nice with
gl_SampleMask writes but that's a problem for when we understand the
hardware better.

Fix a bug in BIND_PIPELINE XML reported by Dougall, which cleans up
a bit of both decoder and driver.
Instead of...
* 17 bytes BIND_PIPELINE (17)
* An unused 8 byte record (25)
* A set of N 8 byte records (25 + 8 * N)
* Oops, 1 byte too many! One just disappeared (24 + 8 * N)
It seems to instead be
* 24 bytes BIND_PIPELINE (24)
* A set of N 8 byte records (24 + 8 * N)
without the sentinel record. These means the 8 byte records themselves
are shuffled, with the high byte of the pointers split from the low
word, but that's less gross than an off-by-one.
It's still not clear what the last 8 bytes of the BIND_VERTEX_PIPELINE
structure mean, or the last 4 byte of the BIND_FRAGMENT_PIPELINE
structure which seems to be a bit shorter.

Dougall Johnson observed these structures make more sense with indices[]
first in the entries and indices[] absent from the header. Then the
sentinel entry disappears, nr_entries makes more sense, and a few magic
numbers pop out. Many thanks to Dougall's astute eyes.

This is where it should be rather than having to pass it into the
optimisation pass every time.
It also allows us to call the loop analysis pass without having to
duplicate these options which we will do later in this series.
