-fsanitize=undefined configure option?

jwe,

Is this extra level of code checking useful enough to make it worthwhile to
put in a configure option for it?  We already have one for -fsanitize=address.

 --enable-address-sanitizer-flags
                          add extra -fsanitize=address and
                          -fno-omit-frame-pointer options to CFLAGS, CXXFLAGS,
                          and LDFLAGS

Then build-bots could simply run with a a different configure option,
rather than hand-modifying all of the FLAG variables.
