add a flag to identify commutative & associative ops
The way how the functions doing the simplification of commutative
or associative binops are called is simple but complicates the
simplification of a specific binop.
Fix this by adding a flag to the opcode table to identify the
commutative and the associative binops and using this flag
to call or not the functions doing the corresponding simplification.
