Instead of trying to detect which sanitizer we run on, just allow the
output that any sanitizer would produce.
Note that the regular expression syntax is pretty limited, so we cannot
express this as a single regex.

This removes the single use of {V8_USE_UNDEFINED_BEHAVIOR_SANITIZER}
again, but for completeness I leave it in {macros.h} for now.
