Simon Hausmann 0d19e2d9b9 Add support for global aliases
When exporting an global multiple times under different names, make sure
that they alias in the generated code.

As a consequence, the compiler maintains the original unique name and in
Rust and C++ makes only the exported names public. In the interpreter
the internal name is theoretically still accessible from the outside.
