  Log Message:
  -----------
  [mlir][PassManager] Only reinitialize the pass manager if the context registry changes

This prevents needless reinitialization for clients that want to reuse a pass manager multiple times. A new `getRegisryHash` function is exposed by the context to give a rough indicator of when the context registry has changed.
