I don't like let chains cause they are not yet supported by rustfmt rust-lang/rustfmt#5203. So I'll just keep it like this for now..

The scope discovery and symbol resolution stages did not handle match cases before. This PR implements this. Match cases are similar to declarations in that bindings inside the pattern are added to the child scope. Consequently, match cases create their own scopes.
Closes #637.
