This actually supports more of the extension than the LLVM backend but we
can't enable it because ACO doesn't work with all stages yet.
With more of it enabled, some CTS tests fail because our 64-bit sqrt
is very imprecise. I can't find any precision requirements for it
anywhere, so I'm thinking it might be a CTS issue.

Large programs, e.g. gnome-shell and firefox, may tax the
addressability of the Medium code model once a (potentially unbounded)
number of dynamically generated JIT-compiled shader programs are
linked in and relocated. Yet the default code model as of LLVM 8 is
Medium or even Small.
The cost of changing from Medium to Large is negligible:
- an additional 8-byte pointer stored immediately before the shader entrypoint;
- change an add-immediate (addis) instruction to a load (ld).

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.
