Add global labels
These are labels that are declared by prefixing a '#' symbol to the
name, and it allows the label to be declared at the global scope instead
of the current one.
This is a feature which is not to be abused so to not make scopes
pointless, but it can be quite handy with some optimizations while not
abandoning scopes completely.
