To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium. Since u_format used
util_copy_rect(), I moved that in there, too.
I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.

Previously, instruction selection had two kinds of booleans:
1. divergent which was per-lane and stored in s2 (VCC size)
2. uniform which was stored in s1
Additionally, uniform booleans were made per-lane when they resulted
from operations which were supported only by the VALU.
To decide which type was used, we relied on the destination size,
which was not reliable due to the per-lane uniform bools, but it
mostly works on wave64.
However, in wave32 mode (where VCC is also s1) this approach
makes it impossible keep track of which boolean is uniform and
which is divergent.
This commit makes all booleans per-lane.
The resulting excess code size will be taken care of by the optimizer.

Commit "1c2bf82d24a glsl: disable lower_fragdata_array() for NIR drivers"
disabled the GLSL IR lowering that turned gl_FragData from an array into a
collection of scalar outputs under the assumption that this was already being
handled properly elsewhere, however there are some corner cases where NIR
would fail to do this, leaving gl_FragData[] as an array variable. This can
break backends that assume that all their outputs will be scalar and use the
variable definitions from the shader to do their output setup, such as the
case of V3D.
At least one corner case was found in some Portal shaders from shader-db, where
NIR would optimize out the full body of a fragment shader. In this scenario,
the empty shader would keep the original array definition of gl_FragData[],
causing the backend to assert.
We need to do this late enough for it to be effective, since doing it in
st_nir_preprocess does not fix the original problem.

On ICL we have the src1 restriction which is applied through
fix_byte_src() and potentially changes the type of the operands from 8
to 32 bits. When this change happens, we fall into the "else if
(bit_size < 32)" case and miscompute src_type because it takes into
consideration bit_size (8) instead of the adjusted size of temp_op
(32). This results in the shader reading unused memory, giving us
mostly failures, but occasional passes due to whatever was already in
the registers we were reading.
This commit fixes a lot of dEQP subgroup i8vec2 tests on ICL, such as:
dEQP-VK.subgroups.arithmetic.compute.subgroupadd_i8vec2
This can also be verified by simply changing fix_byte_src() to apply
on all platforms.

This is less complicated than previously thought. Note we have no way of
specifying the work register count for blend shaders; it must be
strictly less than the work register count of the corresponding fragment
shader (which is fine since we force the fragment shader to report a
count of 16 with a blend shader as a major hack until we get register
pressure down for blend shaders).

For pre-fs-dispatch texture fetch, we need to assign bary_ij to r0.x,
even if it is not used in the shader (ie. only varying use is for tex
coords). But if, for example, gl_FragCoord is used, it could get
assigned on top of bary_ij, resulting in a GPU hang.
The solution to this is two-fold: (1) the inputs/outputs rework has the
benefit of making RA realize bary_ij is a vec2, even if there are no
split/collect instructions (due to no varying fetches in the shader
itself). And (2) extend the live ranges of meta:input instructions to
the first non-input, to prevent RA from assigning the same register to
multiple inputs.
Backport note: because of (1) above, a better solution for 19.3 would be
to revert f30c256ec05.

At the ir3 level, we would assume that we could use wrmask to mask
off other components of an instruction returning a vecN when they are
not used. Which would let RA use components not written for other live
values. But this is only true for tex instructions.

Allow inputs/outputs to be vecN (ie. whatever their actual size is), and
use split to get scalar components of inputs, and collect to gather up
scalar components of outputs.
The main motivation is to simplify RA, by only having to consider split/
collect to figure out where values need to land in consecutive scalar
registers, rather than having to also deal with left/right neighbors.
Because of varying packing, and the resulting fractional location
(location_frac), to implement load_input/store_output, it is still
convenient to have a table of scalar inputs/outputs. We move this to
the compile ctx (since it is only needed for nir->ir3).
