Nothing uses it. I *looks* like _mesa_copy_linked_program_data()
copies it somewhere useful however that function is called before
the value are even initialised.

We update the program copy of info at the end of linking. During linking
we should use the shader copy. This change is required to avoid updating
both in the following patch.

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.

Commit 719bf30165 added this removal code with the following
justification:
"The GLSL 4.10 rules for redeclaration of built-in interface blocks
(which we've chosen to regard as clarifications of GLSL 1.50) only
require gl_PerVertex blocks to match in shaders that actually use
those blocks. The easiest way to implement this is to detect
situations where a compiled shader doesn't refer to any elements of
gl_PerVertex, and remove all the associated ir_variables from the
shader at the end of ast-to-ir conversion."
However the intention is to avoid matching a redeclared block with
gl's default block if unused. We are still required to do block
matching in the shader should the block be redeclared, even if unused.
So with this change we only remove the block if it is both unused
and not redeclared.
The existing glsl IR code managed to avoid failing CTS tests for this
due to seemingly magical or hacky use of the symbol table but fixing
it will make things much clearer, and also allow a nir version of
this validation in a following patch.
