Determine the upwinded wLC(ixL) and wRC(ixR) from w. the wCT is only used when PPM is exploited.
RJV: the PPM reconstruction residual and the alternation switch
scratch for a face-value velocity limiter (weno5/wenoz5/mp5): those routines write every variable at once, so they are run into a copy and only the momentum rows kept. Allocated only when such a limiter is actually requested.
