LibRegex: Do not continue searching input when the sticky bit is set

Browse source 
This partially reverts commit a962ee020a.

When the sticky bit is set, the global bit should basically be ignored
except by external callers who want their own special behavior. For
example, RegExp.prototype [ @@match ] will use the global flag to
accumulate consecutive matches. But on the first failure, the regex
loop should break.
