For undefined bits, print out information about the possible tiles they could affect even though a specific resource and function could not be determined for the bit in the Project X-Ray database. If no possible tiles could be found, make that clear.
For some CLB functions (such as CLKINV) there is not cell mapped onto the BEL. We need to properly detect these bits and classify them correctly, making it clear that there isn't a design resource related to that BEL.
