Michael Kuperstein a4fe29414d [TLI] Refactor "is integer division cheap" queries.
This removes the isPow2SDivCheap() query, as it is not currently used in
any meaningful way. isIntDivCheap() no longer relies on a state variable
(as all in-tree target set it to false), but the interface allows querying
based on the type optimization level.
