[SCEVExpander] Use IRBuilderCallbackInserter to call rememberInstruction.

Authored by fhahn on Jul 22 2020, 7:29 AM.



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.

This is indeed in-line with what i imagined, and it obviously looks cleaner that way, so LGTM.
Not sure if you want to also wait for other reviewers.
