IR: Implement Value::mergeUseLists() iteratively This avoids stack overflows when the the compiler does not perform tail call elimination. Apparently this happens for MSVC with the /Ob2 switch which may be used by external code including this header. Reported by and based on a patch from Jean-Francois Riendeau.
