    M mlir/unittests/Pass/PassManagerTest.cpp

  Log Message:
  Fix MLIR pass manager initialization: hash the pass pipeline to detect when initialization is needed

The current logic hashes the context to detect registration changes and re-run
the pass initialization. However it wasn't checking for changes to the
pipeline, so a pass that would get added after a first run would not be
initialized during subsequent runs.
