Marc Alff ed3a57fea3 Bug#45194 mysql_upgrade deletes existing data in performance_schema database/schema
Before this fix, mysql_upgrade would always drop and re create
the performance_schema database.
This in theory could destroy user data created using 5.1 or older versions.

With this fix, mysql_upgrade checks the content of the
performance_schema database before droping it.
