Future type systems (pipelining + high II) assume a rough correspondence between C operation latency and the their naive handshake counterpart. While very often true, specific optimization patterns may reduce the latency drastically, drastically reducing the effectiveness of latency-guided type systems. This PR therefore introduces a new type system that is meant to stop the generator from producing the most common patterns that lead to latency reductions. Concretely, the type system implements two patterns in this PR: * One to avoid turning a mul by a constant into an adder-tree * One to avoid turning a mul by an operand known to be 0 or 1 into a select statement
