This will need to be set to true when the GLSL linker lowers IO, which
can later be unlowered by st/mesa, and then drivers can lower it again
without load_interpolated_input. Therefore, it can't be a global
immutable option.

Instead of having separate lists of variables, roughly sorted by mode,
use a single list for all shader-level NIR variables. This makes a few
list walks a bit longer here and there but list walks aren't a very
common thing in NIR at all. On the other hand, it makes a lot of things
like validation, printing, etc. way simpler. Also, there are a number
of cases where we move variables from inputs/outputs to globals and this
makes it way easier because we no longer have to move them between
lists. We only have to deal with that if moving them from the shader to
a nir_function_impl.

Vulkan allows fragment shaders to read gl_ClipDistance[], in which
case the SPIR-V compiler inserts a single compact array variable for
VARYING_SLOW_CLIP_DIST0 and the lowering should not try to inject
its own variables, but instead work in terms of the existing one.
Vulkan drivers are expected to call this with use_clipdist_array set
to true to be consistent with this setup.

the naming is a bit confusing no matter how you look at it. Within SPIR-V
"global" memory is memory accessible from all threads. glsl "global" memory
normally refers to shader thread private memory declared at global scope. As
we already use "shared" for memory shared across all thrads of a work group
the solution where everybody could be happy with is to rename "global" to
"private" and use "global" later for memory usually stored within system
accessible memory (be it VRAM or system RAM if keeping SVM in mind).
glsl "local" memory is memory only accessible within a function, while SPIR-V
"local" memory is memory accessible within the same workgroup.

In i965 and iris, I'd rather do this lowering early and work with
