        <rdar://problem/5368990> REGRESSION: newsgator.com sign-on 6x slower than Safari 3 beta due to GC changes (14808)

        * kjs/string_object.cpp:
        (KJS::replace): if the string didn't change (very common in some cases) reuse the original string value.
        (KJS::StringProtoFunc::callAsFunction): Pass in the StringImp* when replacing, not just the UString.
        * kjs/string_object.h:
        (KJS::StringInstance::internalValue): covariant override to return StringImp for convenience
