This is a prerequisite for enabling nir_opt_varyings for all gallium
drivers.
nir_lower_io_passes (called by the GLSL linker) only uses NIR options
to lower indirect IO access before lowering IO and calling
nir_opt_varyings.
Most drivers report full support for indirect IO and lower it themselves,
which prevents compaction of lowered indirectly accessed varyings because
nir_opt_varyings doesn't touch indirect varyings.

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.

No driver supports urol/uror on all bit sizes. Intel gen11+ only for 16
and 32 bit, Nvidia GV100+ only for 32 bit. Etnaviv can support it on 8,
16 and 32 bit.
Also turn the `lower` into a `has` option as only two drivers actually
support `uror` and `urol` at this momemt.
Fixes crashes with CL integer_rotate on iris and nouveau since we emit
urol for `rotate`.
v2: always lower 64 bit

This is actually a no-op on AMD, so we really don't want to lower it to
something more complicated. There may be a more efficient way to do
this on Intel too. In addition, in the future we'll want to use this for
lowering boolean reduce operations, where the inverse ballot will
operate on the backend's "natural" ballot type as indicated by
options->ballot_bit_size, instead of uvec4 as produced by SPIR-V. In
total, there are now three possible lowerings we may have to perform:
- inverse_ballot with source type of uvec4 from SPIR-V to inverse_ballot
with natural source type, when the backend supports inverse_ballot
natively.
- inverse_ballot with source type of uvec4 from SPIR-V to arithmetic,
when the backend doesn't support inverse_ballot.
- inverse_ballot with natural source type from reduce operation, when
the backend doesn't support inverse_ballot.
Previously we just did the second lowering unconditionally in vtn, but
it's just a combination of the first and third. We add support here for
the first and third lowerings in nir_lower_subgroups, instead of simply
moving the second lowering, to avoid unnecessary churn.
