(I also can't help but wonder why do we need that
`m_forward_decl_compiler_type_to_die` in the first place, given that the
`ClangASTMetadata` associated with the type already contains a user ID, which
should allow us to retrieve original DIE. I know this isn't related to your
patch, I'm just writing it in case you or someone has any thoughts on this.)
