Summary [Yarr] Improve processing of an alternation of strings

Several web applications use RegExp's to parse tokens. For example /^(?:if|then|else|switch|break|case|which|do|for)/. Since an anchor regular expression like this is only evaluated once, we can simplify the processing of a string list like this.
