    M mlir/lib/Pass/Pass.cpp
    M mlir/lib/Pass/PassStatistics.cpp

  Log Message:
  -----------
  Decouple OpPassManager from the the MLIRContext (NFC)

This is allowing to build an OpPassManager from a StringRef instead of an
Identifier, which enables building pipelines without an MLIRContext.
An identifier is still cached on-demand on the OpPassManager for efficiency
during the IR traversal.
