History
Owen Anderson 645fd68c5c Fix an infinite loop in InstCombine when an instruction with no users and side effects can be constant folded. 
ReplaceInstUsesWith needs to return nullptr when the input has no users,
because in that case it does not mutate the program.  Otherwise, we can
get stuck in an infinite loop of repeatedly attempting to constant fold
and instruction with no users.
