4695bebc79 nir: Drop nir_dest
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.

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.

This makes the code a bit less verbose, so let's use the helpers.
