Please re-add the reference execution output files:

• regression-tests/test-results/apple-clang-14/mixed-bugfix-for-ufcs-non-local.cpp.execution
• regression-tests/test-results/apple-clang-14/pure2-bugfix-for-non-local-function-expression.cpp.execution
• regression-tests/test-results/apple-clang-14/pure2-bugfix-for-ufcs-noexcept.cpp.execution
• regression-tests/test-results/apple-clang-14/pure2-bugfix-for-ufcs-sfinae.cpp.execution

Despite the fact they are empty they are useful for automated testing.
