[PATCH 090/125] gccrs: Remove extern block scoping

[Arthur Cohen]

From: Pierre-Emmanuel Patry <pierre-emmanuel.pa...@embecosm.com>

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.
