…royBridgedStorage. Extend the lifetime of bridgedStorage until after the contents are deinitialized. When two threads race in withUnsafeBufferOfObjects, the loser uses _destroyBridgedStorage to destroy its candidate buffer, and we need to extend the lifetime of that buffer since the parameter is the only extant reference to it. rdar://99565140 (cherry picked from commit acbcd5f)
