Bruce Evans 7c24ca50f8 Quick fix for a pessimization in rev.1.194. An extra i/o instruction
was added to the fast path to support the COM_IIR_RXRDYBUG() case even
when that case is not configured.  This increased the relative overhead
of sio input by almost 25% in the worst case and by 2-3% in the usual
case (usually only about 0.2% absolute per port at 115200 bps).  The
quick fix is to significantly pessimize only the COM_IIR_RXRDYBUG()
case.
