        RegularExpression::match should not crash when a null string is passed

        RegularExpression::match used to pass null subject strings to
        jsRegExpExecute causing an ASSERT failure and then a crash.
        There is no need to fix also RegularExpression:search and
        RegularExpression::searchRev as they just call
        RegularExpression::match.

        * platform/text/RegularExpression.cpp:
        (WebCore::RegularExpression::match): Return -1 if the string is null.
