    Fix a handful of other leaks seen on the buildbot.

    * runtime/UStringImpl.h:
    (JSC::UStringOrRopeImpl::deref): Delegate through to the subclass version of deref to ensure that
    the correct cleanup takes place.  This function previously featured some code that attempted to
    skip deletion of static UStringImpl's.  Closer inspection revealed that it was in fact equivalent
    to "if (false)", meaning that UStringImpl's which had their final deref performed via this function
    were leaked.
