Do not deserialize type aliases in compatibility mode

When "-language-version 1.0" is specified in command line arguments, the
compiler should not be able to see the declarations of type aliases in
libraries, because that corresponds to the behavior of the compiler of version
1.0. Note that type aliases are _completely invisible_ in this mode (i.e.
"unresolved reference" is reported) because they must not interfere with the
classifier resolution
