Instead, we replace it directly with nir_def. We could replace it with
nir_dest but the next commit gets rid of that so this avoids unnecessary
churn. Most of this commit was generated by sed:
sed -i -e 's/dest.dest.ssa/def/g' src/**/*.h src/**/*.c src/**/*.cpp
There were a few manual fixups required in the nir_legacy.c and
nir_from_ssa.c as nir_legacy_reg and nir_parallel_copy_entry both have a
similar pattern.

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++.

Done by hand at each call site but going very quickly with funny Vim motions and
common regexes. This is a very common idiom in NIR.

This commit drops legacy atomic support from core passes where we can simply
delete switch cases with no other changes. As such it's separated from the
more complex pass-specific commits for ease of review.

Lots of passes can be made unified-atomics-aware simply by adding extra cases in
their switch statements. This commit fixes a bunch of passes.

nir_foreach_src() bails after cb returns false for any src. Which isn't
the behavior we were looking for. Move progress flag to state struct
instead, so we don't skip visiting some sources.

Now that num_ubos is correctly maintained, we can just trust it. Fixes an
assertion failure in freedreno I triggered on
dEQP-GLES31.functional.ubo.random.all_per_block_buffers.1 for reasons I
don't really understand.

Instead of having separate lists of variables, roughly sorted by mode,
use a single list for all shader-level NIR variables. This makes a few
list walks a bit longer here and there but list walks aren't a very
common thing in NIR at all. On the other hand, it makes a lot of things
like validation, printing, etc. way simpler. Also, there are a number
of cases where we move variables from inputs/outputs to globals and this
makes it way easier because we no longer have to move them between
lists. We only have to deal with that if moving them from the shader to
a nir_function_impl.
