`Res::SelfTy` currently has two `Option`s. When the second one is `Some` the first one is never consulted. So we can split it into two variants, `Res::SelfTyParam` and `Res::SelfTyAlias`, reducing the size of `Res` from 24 bytes to 12. This then shrinks `hir::Path` and `hir::PathSegment`, which are the HIR types that take up the most space. |
