nir: Skip emitting no-op movs from the builder.
Having passes generate these is just making more work for copy
propagation (and thus probably calling more optimization passes)
later. Noticed while trying to debug nir_opt_algebraic()
top-to-bottom having O(n^2) behavior due to not finding new matches in
replacement code.
