Vasileios Porpodas e39d2a4630 [SLP] Look-ahead operand reordering heuristic. ...

Summary: This patch introduces a new heuristic for guiding operand reordering. The new "look-ahead" heuristic can look beyond the immediate predecessors. This helps break ties when the immediate predecessors have identical opcodes (see lit test for an example).
