The lowered LS and NGG stages use local_invocation_index and they
can benefit from the unsigned upper bound because they can emit a
less expensive integer multiplication instruction.
This was working in the past, but accidentally borked by a refactor.

Consider the following sequence in a shader:
b = p_extract a
c = v_mad_u32_u16 b, X, 0
The optimizer applies extract, resulting in:
c = v_mad_u32_u16 a, X, 0 (correct)
Then it mistakenly turns that into:
c = v_mul_u32_u24 a, X, 0 (incorrect)
In this case, the p_extract is applied to v_mad_u32_u16 by
apply_extract. After this, we can no longer be sure that
the operands are still 16 or 24-bit, so we have to remove
this flag.

Mesh shader outputs are either:
- non-array builtins
- array builtins that are either per-primitive or per-vertex
- user-defined outputs that must be either per-primitive or per-vertex
So we can identify any array output as "arrayed" for the purposes of
I/O lowering.

Per-primitive is similar to per-vertex attributes, but applies to all
fragments of the primitive without any interpolation involved.
Because they are regular input and outputs, keep track in shader_info
of which I/O is per-primitive so we can distinguish them after deref
lowering. These fields can be used combined with the regular
`inputs_read`, `outputs_written` and `outputs_read`.

Previously, the optimization to use v_mul_lo_u16 for
32bit multiplications was done in instruction_selection.
This was moved to the optimizer to ease some case distinctions.
The mixed results are due to increased use of SDWA.

This partially reverts commit 4d9acfa533.
The original patch said:
"Python 3 handles unicode strings by default, so we can drop all that."
But this breaks building on RHEL 7 (or similiar) since python3 support
on is much more limited than newer distros. Backporting all the needed
python 3 libraries to EL7 is a pretty big task, and isn't very easy to
maintain.
For workstation purposes, we need the AMD MM/GL driver building on RHEL
7, so only src/util/driconf_static.py needs to be reverted.

With this code, we end up generating code such as:
if (!strcmp(extensions[i].extensionName, "VK_KHR_maintenance1")) {
if (VK_MAKE_VERSION(1,2,0) >= screen->vk_version) {
info->have_KHR_maintenance1 = true;
} else {
info->have_KHR_maintenance1 = true;
}
}
That's clearly nonsense, as it does the same thing in the true and false
case. So let's instead try to walk the Vulkan versions up to the one
we're using in a separate pass, and add all extensions that were made core
in that version.

nir_src_as_const_value can return null pointers, and in other places we
at least assert for this. So let's do that here as well, which makes
Coverity a bit less paranoid.
While we're at it, avoid duplicating the nir_src_as_const_value call to
the same source.

We're using this variable outside of assert, so this shouldn't apply
here.
