  Log Message:
  -----------
  [StandardInstrumentations] Verify function doesn't change if analyses are preserved

Reuse StructuralHash and allow it to be used in non-expensive checks builds.

Move PreservedAnalysisChecker further down StandardInstrumentations so other Instrumentations (e.g. printing) have a chance to run before PreservedAnalysisChecker crashes.
