It saves addressing math, but may cause multiple loads to be done and
bcseled due to NIR not giving us good address alignment information
currently. I don't have any workloads I know of using non-const-uploaded

The vma_heap allocator was originally designed to prefer high addresses
in order to find bugs in ANV's high address handling. However, there
are cases where you might want the allocator to prefer lower addresses
for some reason. This provides a configure bit for exactly this

The GC880 on iMX6DL indicates in it's minorFeatures2 register that it
does support SEAMLESS_CUBE_MAP, however when the TE.SAMPLER_CONFIG1
VIVS_TE_SAMPLER_CONFIG1_SEAMLESS_CUBE_MAP bit is set on GC880 on iMX6DL,
the result is corrupted image. In particular, the following ~112 dEQPs
are affected and fail:
dEQP-GLES2.functional.texture.filtering.cube.*
This only happens on MX6DL GC880, MX6Q GC2000 and STM32MP1 GC400(GCnano)
do not report the minorFeatures2 SEAMLESS_CUBE_MAP bit and ignore the
TE_SAMPLER_CONFIG1 VIVS_TE_SAMPLER_CONFIG1_SEAMLESS_CUBE_MAP bit (note
that ss->seamless_cube_map is unconditionally set by mesa at times even
PIPE_CAP_SEAMLESS_CUBE_MAP_PER_TEXTURE returns 0), so there is no visible
problem and there are no failing dEQP tests on the GC2000 and GCnano.
This might imply that the minorFeatures2 SEAMLESS_CUBE_MAP has some
different meaning on GC880 or the SEAMLESS_CUBE_MAP behaves differently
on the GC880.
This patch does not set the SEAMLESS_CUBE_MAP bit on hardware which does
not indicate support for seamless cube map and on GC880, which results
in reduction in failed dEQPs: 635 to 186 on GC880, 274 to 270 on GC2000
and no change on GC400(GCnano).

We can no longer assume that `state->ranges[0]` is block 0. It *often*
is, but when we encounter a "real" ubo that we lower to `load_uniform`
before a block 0 `load_ubo`, it could end up another entry in the table.
Resulting in the second pass after gathering ubo ranges, not finding a
valid range. Which results in a `load_ubo` for a thing that is not
actually a ubo making it's way into ir3 frontend. Resulting in grabbing
what we think is a ubo address out of some unrelated const register, and
trying to dereference that. Which as you can imagine, fails in amusing
ways.

This commit fixes a GS regression introduced in !4562 where
ir3's GS lowering pass was moved from common code (ir3_nir) to
freedreno-specific code (ir3_shader). For GS support in turnip, we
need to add the GS lowering pass back in, this time in tu_shader.
As for the nir_gather_info change, the GS lowering pass has always
introduced a discard_if intrinsic into the GS. Previously, we simply
ran nir_shader_gather_info before GS lowering, but now since we lower
the GS before we need to remove the assertion that only a FS can use
the discard_if intrinsic.

Using non-write flags is pretty dubious -- it means the kernel tracking an
array of read-only consumers of the BO and having exclusive consumers wait
on each reader's fence. It allows multiple readers through dma-bufs to do
work in parallel, but at the cost of kernel CPU time and memory management
of the shared array. Other drivers have dropped this distinction since
dma-buf sharing is usually producer-consumer, not producer-two-consumers,
and the userspace and kernel space tracking is expensive.
For us, this lets us drop the flags passed in for relocs and tracked in
the ringbuffer reloc lists. The end result of the flags reduction work is
