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.
