Help text

This option enables all of the sanitizers involved in integer overflow (wrap-around) mitigation: signed-integer-overflow, unsigned-integer-overflow, implicit-signed-integer-truncation, and implicit-unsigned-integer-truncation. This is currently limited only to the size_t type while testing and compiler development continues.
