nir_opt_algebraic: Don't shrink 64-bit bitwise ops if pack_split is going to be lowered

Otherwise this can cause optimizations to fight resulting in infinite
optimization loops with opt_algebraic, constant_folding, and copy_prop.

Fixes: 368be872 ("nir/algebraic: shrink 64-bit bitwise operations with 0/-1 constant half")
