This brings the sizes down to ``` [src/librustdoc/lib.rs:102] std::mem::size_of::<Item>() = 520 [src/librustdoc/lib.rs:102] std::mem::size_of::<ItemKind>() = 248 ``` from ``` [src/librustdoc/lib.rs:102] std::mem::size_of::<Item>() = 608 [src/librustdoc/lib.rs:102] std::mem::size_of::<ItemKind>() = 336 ```
This reduces the size from ``` [src/librustdoc/lib.rs:102] std::mem::size_of::<Item>() = 520 [src/librustdoc/lib.rs:102] std::mem::size_of::<ItemKind>() = 248 ``` to ``` [src/librustdoc/lib.rs:102] std::mem::size_of::<Item>() = 432 [src/librustdoc/lib.rs:102] std::mem::size_of::<ItemKind>() = 160 ```
