combine: Don't make log_links for pc_rtx (PR84780 #c10)

distribute_links tries to place a log_link for whatever the destination
of the modified instruction is.  It shouldn't do that when that dest
is pc_rtx, which isn't actually a register.

* combine.c (distribute_links): Don't make a link based on pc_rtx.
