Now that nir_const_value is a scalar, there's no reason why we need
multiple paths here and it's just extra paths to keep working. While
we're here, we also add a vtn_fail_if check that component indices are
in-bounds.

All of the callers for this function are looking at interpolation
qualifiers and want to make sure they're declared flat. Any 64-bit
integer inputs need to be flat. It's also makes the function make more
sense since "integer" is fairly generic.

Even if only variables access flags are changed, the existing NIR
infrastructure expects metadata to be explicitly preserved, so do
that. Don't care about avoiding preserve to be called twice since the
cost is negligible.
This scenario can be triggered by dead variables, and also by other
intrinsics that read the variables -- but not cause progress to be
made when processing the intrinsics.

The disk cache code tries to allocate a 256 Kbyte buffer on the stack.
Since musl only gives 80 Kbyte of stack space per thread, this causes a
trap.

Right now, this just deduces when we can arbitrarily reorder SSBO and
image loads, matching the existing logic in radeonsi's TGSI->LLVM pass.
This approach can't handle some things that nir_opt_copy_prop_vars can,
but it can handle images, and with GCM it lets us hoist reads outside of
loops. We can also pass this information to LLVM which lets it do its
own optimizations on it.
This is GLSL only as I haven't tested it on Vulkan yet, and it would
probably need a few changes to work there.

The spec explicitly says that volatile writes can't be removed and
volatile reads do not guarantee that the same value will still be around

We were completely ignoring these before, except for putting them on
variables. While we're here, don't set access qualifiers when converting
to bindless since glsl_to_nir will already have set a more accurate
qualifier that includes any qualifiers on struct members that are
dereferenced.

inaccessiblememonly means that it doesn't modify memory accesible via
normal LLVM pointers. This lets LLVM's dead store elimination, memcpy
forwarding, etc. ignore functions with this attribute. We don't
represent descriptors as pointers, so this property is always true of
buffer and image stores. There are plans to represent descriptors via
pointers, but this just means that now nothing is inaccessiblememonly,
as LLVM will then understand loads/stores via its usual alias analysis.
Radeonsi was mistakenly only setting it if the driver could prove that
there were no reads, and then it was cargo-culted into ac_llvm_build
and ac_llvm_to_nir. Rip it out of everything.

Do not offer a hardware drm backed egl device if no render node

egl device. On top it issues a warning that is actually missleading.
There are finally more error paths that can fail on the way to a
hardware backed egl device. Fixing all of them would kind of require
opening the drm device and see if there is a usable driver associated
with the device. The taken approach avoids a full probe and fixes at
least this kind of problem on kvm virtualization hosts I observe here.

This combines the two cmdstream bits "is_3d" and "is_not_cubemap" into a
single 2-bit texture target selection, noticing it's the same as the
2-bit selection in Midgard and Bifrost texturing ops. Accordingly, we
share this definition and add the missing entry for 1D/buffer textures.
This requires a nontrivial (but functionally similar) refactor of all
parts of the driver to use the new definitions appropriately.
Theoretically, this should add support for buffer textures, but that's
obviously not tested and probably wouldn't work.
While doing so, we notice the sRGB enable bit, which we document and
decode as well here so we don't forget about it.
