Decide on (and implement) which parts of the AST can get stability attributes

For earlier discussion, see rust-lang/rust#8967

This issue was labelled with: A-attributes, A-lint, B-RFC in the Rust repository

---

As of #8921, the compiler checks the attributes on structs, enum variants (not enums themselves) and functions. Definitely required: methods (#8961) and mods (#8962).

Up for discussion:

• traits
• enums
• impls (both impl Type and impl Trait for Type)
• struct fields
• type aliases.
• foreign fns
• anything else that can take attributes in the ast

(Part of #6875.)

This is implemented long ago.
Everything that can be named is checked for stability, except for reexports (tracked by rust-lang/rust#23937).
