Add --enable-ubsan/ENABLE_UBSAN for UndefinedBehaviorSanitizer
UndefinedBehaviorSanitizer (UBSan) can catch a lot of issues
(out-of-bounds memory access, integer overflows, undefined shifts,
etc.) and is recommended during development using GCC or Clang. Add an
option for it (similar to ASAN support).
