[PATCH] D126455: [FuncSpec] Make the Function Specializer part of the IPSCCP pass.

Good point. Running the LoopInfo analysis when we do not specialize adds unnecessary compile time overhead. After some investigation I found that notifying the users after replacing a value (instead of notifying only the old users), as well as not removing replaced instructions, both add significant compile time overhead. I am inclined to revert the latter and rework on the former so that markUsersAsChanged can accept a list of users.
