Add regnode EXACTFU_ONLY8
This is a regnode that otherwise would be an EXACTFU except that it
contains a code point that requires UTF-8 to match, including all the
possible folds involving it. Hence if the target string isn't UTF-8, we
know it can't possibly match, without needing to try.
For completeness, there could also be an EXACTFAA_ONLY8 and an
EXACTFL_ONLY8 created, but I think these are unlikely to actually appear
in the wild, since using /aa is mainly about ASCII, and /l mostly will
involve characters that don't require UTF-8.
