This flag is mostly redundant with uses_discard and was only
introduced to implement demote with LLVM when it didn't have

The semantics of discard differ between GLSL and HLSL and
their various implementations. Subsequently, numerous application
bugs occurred and SPV_EXT_demote_to_helper_invocation was written
in order to clarify the behavior. In NIR, we now have 3 different
intrinsics for 2 things, and while demote and terminate have clear
semantics, discard still doesn't and can mean either of the two.
This patch entirely removes nir_intrinsic_discard and
nir_intrinsic_discard_if and replaces all occurences either with
nir_intrinsic_terminate{_if} or nir_intrinsic_demote{_if} in the
case that the NIR option 'discard_is_demote' is being set.

Instead, we replace it directly with nir_def. We could replace it with
nir_dest but the next commit gets rid of that so this avoids unnecessary
churn. Most of this commit was generated by sed:
sed -i -e 's/dest.dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp
There were a few manual fixups required in the nir_legacy.c and
nir_from_ssa.c as nir_legacy_reg and nir_parallel_copy_entry both have a
similar pattern.

We could add a nir_def_bit_size() helper but we use ->bit_size about 3x

sample_mask_agx corresponds directly to the hardware's 2-source instruction, but
it's hard to use correctly and even harder to legalize after the fact, since
it's responsible for not only discard but also late depth/stencil testing. For
our various high-level lowering passes, it's easier to use a one-source discard
(where we don't have to worry about sample masks), which the compiler will
internally lower to the two-source instruction. Introduce such an instruction.

sample_mask_agx maps to the AGX instruction used to write out a sample mask.
api_sample_mask_agx is a system value that returns the value of glSampleMask
(or its Vulkan equivalent), used to lower glSampleMask (etc).
This is distinct from sample_mask_in, which we map to the hardware thing and
AND with this as a lowering.
sample_positions_agx is a system value returning the sample positions in a
packed fixed-point format matching the hardware register, used to lower
gl_SamplePositions.
