this was missed in the original v3d pass, and then the common code port
inherited the bug. (so strictly this fix "should" be backported even farther
back but it won't apply before the Fixes here, and I don't think we do LTS that
far back anyway).
in theory this should fix a corner case with robustness on the gl (but not
vulkan, at least for apple) drivers on broadcom & apple.

rather than try to enumerate everything a driver might want with an unmanageable
collection of booleans, just do a filter callback + data. this ends up simpler
overall, and will allow Intel to use this pass for just 64-bit images without
needing to add even more booleans.
while we're churning the pass signature, also do a quick port to
nir_shader_intrinsics_pass

Instead, we replace every use of it with nir_def. Most of this commit
was generated by sed:
sed -i -e 's/dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp
A few manual fixups were required in lima and the nir_legacy code.

We could add a nir_def_bit_size() helper but we use ->bit_size about 3x
as often as nir_dest_bit_size() today so that's a major Coccinelle
refactor anyway and this doesn't make it much worse. Most of this
commit was generated byt the following semantic patch:
@@
expression D;
@@
<...
-nir_dest_bit_size(D)
+D.ssa.bit_size

Some manual fixup was needed, especially in cpp files where Coccinelle
tends to give up the moment it sees any interesting C++.

Add a pass for bounds checking UBOs, SSBOs, and images to implement robustness.
This pass is based on v3d_nir_lower_robust_access.c, with significant
modifications to be appropriate for common code. Notably:
* v3d-isms are removed.
* Stop generating invalid imageSize() instructions for cube maps, this
blows up nir_validate with asahi's lowerings.
* Logic to wrap an intrinsic in an if-statement is extracted in anticipation of
future robustness2 support that will reuse that code path for buffers.
* Misc cleanups to follow modern NIR best practice. This pass is noticeably
shorter than the original v3d version.
For future support of robustness2, I envision the booleans turning into tristate
enums.
There's a few more knobs added for Asahi's benefit. Apple hardware can do
imageLoad and imageStore to non-buffer images (only). There is no support for
image atomics. To handle, Asahi implements software lowering for buffer images
and for image atomics. While the hardware is robust, the software paths are not.
So we would like to use this pass to lower robustness for the software paths but
not the hardware paths.
Or maybe we want a filter callback?
