Instead of having a hardcoded list of endian-independent format aliases
in the header, generate them from the format definitions.

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.

Note: This change doesn't actually affect dozen a it uses
vk_shader_module_to_nir() so caps will be exposed based on Vulkan
features rather than the manual table.

This removes the need for drivers to handle both versions. The base will
get added once in nir_lower_system_values when converting from deref to
intrinsic and will be replaced by a zero for users not supporting it.

When we don't need emulation of first vertex, base instance, draw ID
sysvals, or triangle fans, we can have very simple command signatures
and indirect arg buffer generation shaders. The next step is to handle
the case where everything can be supported straight from the app's
buffer.

Ubo0 is tricky. It exists if there were any uniforms when
lower_uniforms_to_ubo was run. If we try to run that ourselves,
it might be too late and DCE/remove_dead_variables might've been run,
which removed the uniforms and their accesses, without decrementing
num_uniforms. So we have no good way of knowing whether to declare
ubos from [0, N] or [1, N]. In practice this probably doesn't make
much of a difference but the logic is there so ¯\_(ツ)_/¯
If we use the nir option, then dead code isn't run, and num_uniforms
is a true indicator of whether ubo0 exists or not.
Note that this means we are no longer running this pass for internal
shaders that don't come from the GLSL compiler, so various places are
updated to query the nir info bit that's set by running this pass.

All UAVs which can be accessed via pointer need to be grouped together
starting at base 0, because nir_to_dxil emits the globals array from
[0, size], where size is the input number of globals, as well as one
for each SSBO. Images need to come after that.
Theoretically, nir_to_dxil could emit 3 arrays:
1. Globals
2. Constants
3. Printf
But constants get converted to globals early on so that'd be pretty
tricky to actually detangle.

These were intended to be shared with (e.g.) rusticl, but they're
unused and I expect they will continue to be. The spirv options
are also hardcoded to be what CLOn12 expects.

When a kernel input is a pointer to global or constant memory, it's expected
that the invoker provides the pointer value in the form of
(buffer_index << 32) | offset. The buffer index, however, is statically
knowable in the compiler, as long as a buffer is bound. Since it's
undefined behavior to dereference the pointer with no buffer bound,
we can replace any deref chain that terminates in an access with one
that uses a constant buffer index.

These handles can be emitted in control flow, which means that the handle
might be in a block which does not dominate a block that's processed
later on, which results in incorrect DXIL if we try to reference it.
