Since the integer wrapping sanitizer's behavior depends on its associated .scl file, we must force a full rebuild if the file changes. If not, instrumentation may differ between targets based on when they were built. Generate a new header file, integer-wrap.h, any time the Clang .scl file changes. Include the header file in compiler-version.h when its associated feature name, INTEGER_WRAP, is defined. This will be picked up by fixdep and force rebuilds where needed.
