Handle new visibility types

[kamalmarhubi]

syntex_syntax 0.31 brings a change from

pub enum Visibility {
    Public,
    Inherited,
}

to

pub enum Visibility {
    Public,
    Crate,
    Restricted { path: P<Path>, id: NodeId },
    Inherited,
}

It's unclear if the new variants need handling.

The following code is actually removed by rustfmt:

pub(super) enum WriteState<D> {
    WriteId {
        id: U64Writer,
        size: U64Writer,
        payload: Option<Writer<D>>,
    },
    WriteSize {
        size: U64Writer,
        payload: Option<Writer<D>>,
    },
    WriteData(Writer<D>),
}

When I plop it in tests/target/pub-restricted.rs and run cargo test the output is:

Mismatch at tests/target/pub-restricted.rs:1:

-pub(super) enum WriteState<D> {⏎
-    WriteId {⏎
-        id: U64Writer,⏎
-        size: U64Writer,⏎
-        payload: Option<Writer<D>>,⏎
-    },⏎
-    WriteSize {⏎
-        size: U64Writer,⏎
-        payload: Option<Writer<D>>,⏎
-    },⏎
-    WriteData(Writer<D>),⏎
-}⏎
+⏎

This appears to be a fault of how I handled adding them, which is to say, I didn't: kamalmarhubi@fd38acb#diff-3dbd16223f25e8b5e0bcf099743107e9R74

@tikue I opened #1013 to support it properly. Thanks for the test!

Nice! Quick turnaround😉
