Add `BufferizableOpInterface::verifyAnalysis`. Ops can implement this method to check for expected invariants and limitations. The purpose of this change is to introduce a modular way of checking assertions such as `assertScfForAliasingProperties`. Differential Revision: https://reviews.llvm.org/D120189
