commit 2ad57d7229d1f06f7fe05a9f296725b7269f74d7

    Remove extern block scoping
    
    Remove extern block scoping visit function, use the default visitor visit
    function instead. We do not need scoping for extern block as their
    element shall be visible from the extern block scope.
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-default-resolver.cc (DefaultResolver::visit): Remove
            visitor implementation and scoping.
            * resolve/rust-default-resolver.h: Remove function prototype.
