[PATCH] tree-optimization/102659 - avoid undefined overflow after if-conversion

The following makes sure to rewrite arithmetic with undefined behavior on overflow to a well-defined variant when moving them to be always executed as part of doing if-conversion for loop vectorization. Bootstrapped and tested on x86_64-unknown-linux-gnu. Any comments? Thanks, Richard. 2021-10-
