Implement '==' optimization in beam_ssa_type
`=:=` is faster than `==`, so when they would return the same result,
we want to replace `==` with `=:=`. There is currently such an optimization
in sys_core_fold, but the optimimization will be more effective if
done in beam_ssa_type because beam_ssa_type has better type information.
