When address filters are used, the decoder must detect the end of a filter region (or a branch into a tracestop region) by matching Packet Generation Disabled (TIP.PGD) packets against the object code using the IP given in the packet. However, due to errata SKL014 "Intel PT TIP.PGD May Not Have Target IP Payload", that IP may not be present. Enable the decoder to handle that by adding a new callback function 'pgd_ip()' which indicates whether the IP is not traced, in which case that is the point where the trace was disabled.
