Sanjoy Das 368f045de1 [InstCombine] Refactor out OptimizeOverflowCheck. NFCI. ...

Summary:
This patch adds an enum `OverflowCheckFlavor` and a function
`OptimizeOverflowCheck`.  This will allow InstCombine to optimize
overflow checks without directly introducing an intermediate call to the
`llvm.$op.with.overflow` instrinsics.

This specific change is a refactoring and does not intend to change
behavior.
