This reverts commit 865b9ddae4.
The buffer always reports format PIPE_FORMAT_R8_UNORM so with this patch only
one component would be supported. The original issue is still relevant, but
the fix should be different.

Many of these are now patched; one of them we patch here. Regardless,
this is one less thing to worry about in the code, I suppose.

Don't attempt sampling with HiZ if the sampler lacks support for it. On
ICL, the HW docs state that sampling with HiZ is not supported and that
instances of AUX_HIZ in the RENDER_SURFACE_STATE object will be
interpreted as AUX_NONE.

If the SSA def produced by this instruction is only in the block in
which it is defined and is not used by ifs or phis, then we don't have
a reason to convert it to a register in
nir_lower_ssa_defs_to_regs_block().
The special case for derefs is covered by the general case, so can be
removed: at this point all derefs in the block are
materialized (i.e. the whole deref chain is in the block) and derefs
are not used in phis.
v2: Fix wrong check for if_uses. If there's such an use, the def is
not "local_to_block". (Jason)

Normally gl_nir_lower_samplers_as_deref records info->textures_used
for us, but this pass runs after that, attempting to assign samplers
in the same order as st_atom_texture's external_samplers_used loop
so the stars align and we get the same locations.
Since we're adding textures late, we need to amend info->textures_used.
iris uses info->textures_used to set up texture bindings; this fixes
Piglit's ext_image_dma_buf_import-sample-{nv12,yuv420,yvu420} there.

First, allow the case for negative powers of two. Then ensure that we
use the absolute value of the non-constant value to calculate the
quotient -- this was hinted in the code by the name 'uq'.
This fixes an issue when 'd' is positive and 'n' is negative. The
ishr will propagate the negative sign and we'll use nir_ineg() again,
incorrectly.
v2: First version used only ishr, but that isn't sufficient, since it
never can produce a zero as a result. (Jason)

shader-db's report.py will use this to see when we've changed loop
unrolling behavior on a shader and skip including other stats like
instruction count from being considered for that shader, since they won't
be useful as a proxy for real world performance in that case.

transform feedback draws get the number of vertices from the transform
feedback object. In draw, we'll figure this out with the number of bytes
written divided by the stride. However, it is apparently possible we end
up with a stride of 0 there (not entirely sure it could happen with GL).
Probably when nothing was actually ever written (so we don't actually
have a stride set). Just avoid the division by zero by setting the count
to 0.

Use fstat() only to pre-allocate a big enough buffer.
This fixes a race where if the file grows between fstat() and read()
we would be missing the end of the file, and if the file slims down
read() would just fail.

For a block with a contiguous chunk of 32 vars that don't need updating,
this lets us skip 32 vars at a time. Also, by using bitscan, we only
iterate for each set bit rather than testing them all one at a time.
Looking at perf (with -O0 which is unfortunately necessary to get
reasonable back-traces), this seems to cuts about 50-60% of the time
spent in compute_start_end() which is, itself about 4-6% of the
run-time. In the real world, with a release driver build, this cuts
1.34% off a full shader-db run. (I ran shader-db 5 times in each
configuration).
