c39896b17b nir: Use getters for nir_src::parent_*
First, we need to give the parent_instr field a unique name to be able to
replace with a helper.  We have parent_instr fields for both nir_src and
nir_def, so let's rename nir_src::parent_instr in preparation for rework.

This was done with a combination of sed and manual fix-ups.

Then we use semantic patches plus manual fixups:

    -s->renamed_parent_instr
    +nir_src_parent_instr(s)

4e2830c9ef nir: Clean up nir_op_is_vec() and its callers
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.

65b6ac8aa4 nir: Rename nir_instr_type_ssa_undef to nir_instr_type_undef
We already renamed the type, we just need to rename the enum and the
casting helper functions.

Generated with sed:

    sed -i -e 's/nir_instr_type_ssa_undef/nir_instr_type_undef/g' src/**/*.h src/**/*.c src/**/*.cpp
    sed -i -e 's/nir_instr_as_ssa_undef/nir_instr_as_undef/g' src/**/*.h src/**/*.c src/**/*.cpp

and two tiny whitespace fixups in lima.

6c1d32581a nir: Drop nir_alu_dest
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.

9d81f13a75 nir: Get rid of nir_dest_num_components()
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++.
