[MLIR] [macOS] Cannot build check-mlir on macOS

[Luohaothu]

With CMake config:

-DLLVM_ENABLE_PROJECTS="mlir;clang"
-DLLVM_BUILD_EXAMPLES=ON
-DLLVM_ENABLE_ASSERTIONS=ON
-DLLVM_CCACHE_BUILD=ON
-DLLVM_ENABLE_LLD=ON
-DLLVM_USE_SANITIZER="Address;Undefined"
-DMLIR_INCLUDE_INTEGRATION_TESTS=ON
-DLLVM_USE_SPLIT_DWARF=ON
-DBUILD_SHARED_LIBS=ON
-DCLANG_ENABLE_CIR=ON

and clang compiler on macOS, check-mlir got error message:

                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'TestingConfig' object has no attribute 'lldb_build_directory'

Is this a bug of the script or some misconfig of my environment?
