Set the proper bit when adding clipdist load/store.
It also sets the variable name to match with the CLIPDISTn created.

src and dst can be integer types, and doing an f2f on such types
messes up with the original value. Make sure we keep the original type
when {up,down}sizing the src, dst and out values.

The ffloor@64 case, which lowers to use ffract, is already ignored if
nir_lower_dfract is set. Do the same thing for ftrunc@64 and ffract@64
and let nir_lower_doubles take care of them directly instead.

Some uses don't have any post-dominator. An example is an atomic that
feeds itself in a loop. No instruction immediately post-dominates
the result of such an atomic because no instruction can strictly
post-dominate itself. This handles that case generally by setting
the root node as the post-dominator for instructions that can't be
reordered.

Previously, nir_opt_varyings was unable to distinguish between
a fully occupied 32-bit flat input and the low part of a 16-bit
flat input, and would assign them the same slot, thereby messing
up both I/O slots in the process.

Due to how mesh shaders work, we'll need a workgroup divergence

Not sure what I was thinking when I wrote this pass (probably not much),
but opt makes more sense and matches other nir passes.
Fold is usually used for constants, and this pass handles more than those.

SPIR-V rules for fmax/fmin scans are *very* stupid.
The required identity is Inf instead of NaN but if one input
is NaN, the other value has to be returned.
This means for invocation 0:
min(subgroupExclusiveMin(NaN), NaN) -> Inf
subgroupInclusiveMin(NaN) -> undefined (NaN for any sane backend)

This "tear" is similar to the original concept of loads/stores tearing,
but across invocations in a wave instead of bytes. Qualcomm seems to
have this problem, at least for some GPUs. This fixes
spec@arb_shader_storage_buffer_object@execution@ssbo-atomiccompswap-int
on a630 once we start relying on divergence analysis for computing
reconvergence properties. For backends that have readFirstInvocation(),
it should be possible to fix the problem by inserting
readFirstInvocation() instead, but a5xx doesn't have it so we can't rely
on it in freedreno.

Otherwise we can end with invalid curson in some cases, specifically,
if we encounter an identity vector and thus neither register
declaration nor swizzle is inserted, it can lead to invalid cursor and a
crash later.
