   Note that this assembly comes from the mssqlsystemresource database, that   
   is the system database that inlcudes all system procedures, catalog views   
   etc.   
      
   I don't know about the mpusqlclrwrapper, and the documentation I find on   
   https://msdn.microsoft.com/en-us/library/microsoft.sqlserver.man   
   gement.shared.mpusql.mpusqlclrwrapper.aspx   
   isn't that detailed. However MPU = Multi-Processor Unit or some such.   
   This is related to what now is known as the Parallel Data Warehouse and   
   which first appeared in the SQL 2008 R2 timeframe. Since that is a   
   specialised version of SQL Server, it is not appearent why it would be   
   loaded on a plain-vanilla instance.
