  1. Specialize ZeroSized constants 

    ZeroSized constants can be represented as `mir::Const::Val` even if
their layout is not yet known. In those cases, CrateItem::body() was
crashing when trying to convert a `ConstValue::ZeroSized` into its
stable counterpart `ConstantKind::Allocated`.

Instead, we now map `ConstValue::ZeroSized` into a new variant:
`ConstantKind::ZeroSized`.
