lgtm

For what it's worth, this issue is not observable from clang because clang does this mangling in the frontend. See https://godbolt.org/z/GM1Evjj3Y, it produces the function name `\01_return_large at 0`. Looking at the code suggests that this is just an accident. It works because it is driven by the AST, which doesn't have the implicit sret parameter.
