Currently there are plenty of instructions that SCEVExpander creates but
does not track as created. IRBuilder allows specifying a callback
whenever an instruction is inserted. Use this to call
rememberInstruction automatically for each created instruction.

There are still a few rememberInstruction calls remaining, because in
some cases Inst::Create functions are used to construct instructions.
