We now have NIR opt_large_constants support in place, so we can flip the
switch and get better optimization before lowering to a constant buffer,
but also avoid having constant data mixed in with the shader's uniforms,
which should lower CPU overhead on affected shaders.
Only a few shaders are affected (<.01% impact across shader-db), but for
those the impact is pretty big:
instructions in affected programs: 748 -> 639 (-14.57%)
nops in affected programs: 364 -> 284 (-21.98%)
non-nops in affected programs: 384 -> 355 (-7.55%)
mov in affected programs: 47 -> 27 (-42.55%)
cov in affected programs: 9 -> 6 (-33.33%)
dwords in affected programs: 932 -> 836 (-10.30%)
full in affected programs: 13 -> 14 (7.69%)
constlen in affected programs: 140 -> 64 (-54.29%)
(ss) in affected programs: 14 -> 15 (7.14%)

Right now if the shader indirects on some large constant array, we see NIR
load_consts (usually from the const file) of its contents into general
registers, then indirection on the GPRs. This often results in register
allocation failures, as it's easy to go beyond the ~256 dwords of
registers per invocation.
By moving the large constants to a UBO, we can load an arbitrary number of
them. They also can be theoretically moved to the constant reg file (~2k
dwords), though you're unlikely to hit this path without an indirect load
on your large constant, and we don't yet let UBO indirect loads get moved
to constant regs.
This possibly won't work out right if we have 16-bit load_constants, but
without other MRs in flight we won't see 16-bit temps to be lowered to
this.
This allows 2 kerbal-space-program shaders to compile that previously
would fail, and fixes the new dEQP-VK and -GLES2 tests I wrote that
dynamically index a 40-element temporary array of float/vec2/vec3/vec4
with constant element initializers.

If you're loading a 32b word from the const file and doing a cov.u32u16
split to two 16bit values, we can't turn that into a reference of a 16-bit
float value directly from the constbuf, because the
CONSTANT_DEMOTION_ENABLE results in a f2f16 operation on the 32-bit value
that we didn't want.

cffdump looks at the following 4 instructions to decide if the shader has
*really* ended, so if we pack data after that (such as turnip's next

In applications using clip planes, set_clip_state is expected to be
implemented in the backend. If it is not defined, it may cause the
application to segfault.
glClipPlane it is not part of GLES 2, so it is not trivial to reverse
engineer if something needs to be done in lima.
Other drivers just define a placeholder implementation for
set_clip_state, so for now let's just define one for lima too.

By default we are using 32bit output type for texture operations,
16bit for shadow.
With this commit we also use the precision info from the sampler (that
is assigned if SPIR-V uses RelaxedPrecision decorator), in order to
use 16bit.
This is a first step as only take into account the precision of the
deref_vars used on the texture operation.
But the decoration can be also applied to other cases, like the result
of the operation. That means that there are ways to infer that the
texture operation can operate at relaxed precision. Those cases would
be handled on following patches.
v2:
* Add directly the return_size on the descriptor_map, instead of
shadow/relaxed_precision.
* Check relaxed precision for images too (Iago)
* Handle the return size for the default sampler
v3:
* Handle different output size for the case of not having a sampler.
* Comment fixes (Iago)
