This helper exists for a very tiny set of use-cases but it's better to
have the helper live in nir.c than hand-roll it elsewhere.

The nir_op_is_vec() helper I added in 842338e2f0 ("nir: Add a
nir_op_is_vec helper") treats nir_op_mov as a vec even though the
semanitcs of the two are different. In retrospect, this was a mistake
as the previous three fixup commits show. This commit splits the helper
into two: nir_op_is_vec() and nir_op_is_vec_or_mov() and uses the
appropriate helper at each call site. Hopefully, this rename will
encurage any future users of these helpers to think about nir_op_mov as
separate from nir_op_vecN and we can avoid these bugs.

The cases in the if are the same as the cases we're using for the early
break. Just check the things and break if it's not a handleable case.

Instead, we replace every use of it with nir_def. Most of this commit

A few manual fixups were required in lima and the nir_legacy code.

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_num_components() helper but we use
ssa.num_components about 3x as often as nir_dest_num_components() 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_num_components(D)
+D.ssa.num_components

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

There is no sensible way to do this. It is a hard requirement that the dest is
initialized with nir_ssa_dest_init immediately after creating the instruction.

Nothing produces them any more, so remove them from NIR. This massively reduces
the size of nir_src, which should improve performance all over.
nir_src size reduced from 56 bytes -> 40 bytes (pahole results on arm64, x86_64
should be similar.)
