A lot of test passes are currently anchored on FuncOp, but this dependency is generally just historical. A majority of these test passes can run on any operation, or can operate on a specific interface (FunctionOpInterface/SymbolOpInterface). This allows for greatly reducing the API dependency on FuncOp, which is slated to be moved out of the Builtin dialect. Differential Revision: https://reviews.llvm.org/D121191
