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.

afa79cd9b8 nir: use imm-helpers
We have to use 1ull instead of 1u because MSVC is stupid...

ded3572947 nir: Use nir_type_convert instead of nir_type_conversion_op
In a future commit, nit_type_conversion_op won't be able to handle i2b
(and in a much later commit f2b), so switch many users to the fully
featured function.

No shader-db or fossil-db changes on any Intel platform.

5beeb3c1db nir: use nir_shader_instructions_pass in nir_lower_alu
Changes:
- nir_metadata_preserve(..., nir_metadata_all) is called when pass doesn't
  make progress
- only metadata of the current function is invalidated (invalidation on
  one function was leaking to successive functions because "progress"
  was not reset)

9d6770d20a nir/lower_alu: drop unnecessary iand on uadd_carry result
uadd_carry returns 1 or 0, so ANDing with 1 is unnecessary. Probably
this was implemented thinking that it was returning a boolean value.

117668b811 nir: Make nir_ssa_def_rewrite_uses take an SSA value
This commit replaces the new_src parameter of nir_ssa_def_rewrite_uses()
with an SSA def, removes nir_ssa_def_rewrite_uses_ssa(), and rewrites
all the users as needed.
