[PATCH] D72009: TableGen: Fix assert on PatFrags with predicate code

This assumed a single pattern if there was a predicate. Relax this a
bit, and allow multiple patterns as long as they have the same class.

      

This was only broken for the DAG path. GlobalISel seems to have
handled this correctly already.
