mir_estimate_pressure often underestimates the register pressure,
letting too many registers be used for uniforms, causing RA to fail.
Mitigate this by demoting some uniforms back to explicit loads to free
up work registers if register allocation fails.

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.

glClipPlane it is not part of GLES 2, so it is not trivial to reverse

Other drivers just define a placeholder implementation for
