If the question is whether `fast-string-match' should return match-data
or the same value as `string-match' we're not only wasting our time here
but in the future as well.  `fast-string-match' (or whatever you want to
call it) has to behave exactly like `string-match' but for leaving the
internal value of match data untouched.
