Looks fine, except that I'd rather go for commit message
along the lines of "INT_LIMIT tries to do what type_max does,
except that type_max doesn't rely upon undefined behaviour;
might as well use type_max() instead"

If you want to credit UBSAN - sure, no problem, just don't
clutter the commit message with that.  As it is, it reads
as "make $TOOL STFU"...
