          REGRESSION: RegEx seems broken for hex escaped non breaking space

        Test: fast/js/regexp-extended-characters-more.html

        * pcre/pcre_exec.c:
        (match): Got rid of utf16Length local variable to guarantee there's no
        extra stack usage in recursive calls. Fixed two places in the PCRE_UTF16
        code that were using the length variable, which is the UTF-8 length of
        a character in the pattern, to move in the UTF-16 subject string. Instead
        they hardcode lengths of 1 and 2 since the code already handles BMP
        characters and surrogate pairs separately. Also fixed some DPRINTF so
        I could compile with DEBUG on.
        (pcre_exec): Changed a place that was checking for multibyte characters
        in the subject string to use ISMIDCHAR. Instead it was using hardcoded
        logic that was right for UTF-8 but wrong for UTF-16.

        * pcre/pcre_compile.c: (pcre_compile2): Fixed a DPRINTF so I could compile
        with DEBUG on.
