Problem Title:
PAR misreports Virtex PCIIOBs as only inputs instead of bidirs.


Problem Description:
The code for automatic placement of SelectIO recognizes PCIIOBs as only inputs, when they may be bid irectional I/Os. This can allow infeasible placements to be created because the output IO standard of a PCIIOB may collide with the output standards of other IOBs placed in the same bank.


Solution 1:
