PHINodes that need to be generated to accommodate a PHINode outside the region due to different output paths need to have their own numbering to determine the number of output schemes required to properly handle all the outlined regions.  This numbering was previously only determined by the order and values of the incoming values, as well as the parent block of the PHINode.  This adds the incoming blocks to the calculation of a hash value for these PHINodes as well, and the supporting infrastructure to give each block in a region a corresponding canonical numbering.
