Loop-invariant code motion is a great optimization to look at when considering corner cases of IR semantics.

 One might be tempted to ignore this problem because the UB on integer overflow is a compiler-only concept; every target supported by the compiler will do the obvious thing and just produce an overflowing result.
 However, there might be other compiler passes running after the optimization we are considering.
