          REGRESSION (r28164): regular expressions can now hang due to lack of a match limit
          <rdar://problem/5636067>

        Test: fast/regex/slow.html

        Slows down SunSpider a bit (about 1.01x); filed a bug to follow up on that:
        http://bugs.webkit.org/show_bug.cgi?id=16503

        * pcre/pcre.h: Changed name of error code to not specifically mention "recursion".
        * pcre/pcre_exec.cpp:
        (match): Replaced the depth limit, MATCH_RECURSION_LIMIT, with a total match looping
        limit, matchLimit. Also eliminated the constants for MATCH_MATCH and MATCH_NOMATCH,
        since they are just true and false (1 and 0).
        (jsRegExpExecute): More of the MATCH_MATCH change.
