control flow graph related:
        - late inlining ; requires name gen support

done - common sub-expression elimination
done - bind normalisation
done - constant folding      ; Q: what is the intended behaviour? ; adjust tests
done - copy propagation      ; Q: what is the intended behaviour? ; adjust tests
done - constant propagation  ; it is related to costant folding as it does limited constant folding
