[MS ABI] Number unnamed TagDecls which aren't externally visible
TagDecls (structs, enums, etc.) may have the same name for linkage
purposes of one another; to disambiguate, we add a number to the mangled
named. However, we didn't do this if the TagDecl has a pseudo-name for
linkage purposes (it was defined alongside a DeclaratorDecl or a
TypeNameDecl).
This fixes PR24651.
