Nick Lewycky 98cd75027c Add a small missed optimization: turn X == C ? X : Y into X == C ? C : Y. This 
removes one use of X which helps it pass the many hasOneUse() checks.

In my analysis, this turns up very often where X = A >>exact B and that can't be
simplified unless X has one use (except by increasing the lifetime of A which is
generally a performance loss).
