"Pure".  Though `pure-string-match' doesn't refer to the match data
at all.  It can refer to many different things.

I see no better name than `string-match-no-data' because it clearly
says that it doesn't set match-data according to three words in its name:
"no", "match", "data".

We already have a very similar name `match-string-no-properties'
which returns a string without text properties.  By analogy
`string-match-no-data' would return the match index without setting
the match data.

What about `inhibit-set-match-data'?
