LibRegex: Apply atomic loop rewrite in one more case

Browse Source 
This commit makes LibRegex's atomic loop rewrite opt also accept cases
where the follow block jumps to the end of the forking block
(which is essentially a loop without a proper header in fancy clothes)

This makes patterns like /([^x]*)x/ where the loop is not _immediately_
followed by a block significantly faster.
