FYI, we are planning to refactor the resource buffer AST tests, see here: https://github.com/llvm/llvm-project/pull/113643#discussion_r1833370629

Maybe there could be a single AST test with multiple run lines that would tests all of the raw buffer combinations using defines and different check-prefixes. Do you want to update this test to be ready for adding the next raw buffer variants or wait until the next buffer class is added?
