Ali Mohammad Pur a962ee020a LibJS+LibRegex: Don't repeat regex match in regexp_exec() ...

LibRegex already implements this loop in a more performant way, so all
LibJS has to do here is to return things in the right shape, and not
loop over the input string.
Previously this was a quadratic operation on string length, which lead
to crazy execution times on failing regexps - now it's nice and fast :^)

Note that a Regex test has to be updated to remove the stateful flag as
it repeats matching on multiple strings.
