#2 has deactivated the replacement algorithm.
maybe we can add this functionality to the dcl after read but before any further processing.
If there is one cube with one input and one output and the input is not used anywhere else and it outputs to only one variable and the output variable is used also as input, then we can replace the this input by the other input, removing the cube (and the original input)

do we have existing checks for state machines???

./pluc 'PIO0_22 <= PIO0_10; PIO0_15 <= PIO0_2 & PIO0_22;' -oc tmp.c
has an issue, output does not show two lots

./pluc 'PIO0_22 <= PIO0_10;' 'PIO0_15 <= PIO0_2 & PIO0_22;' -oc tmp.c
is still better: at least two LUTs are generated
