Some renamings: s/ast_ty/hir_ty and s/StructField/hir::StructField

Browse source 
I think in both cases the new names make the code more understandable.
For `StructField` specifically because there's one in
[`syntax::ast`][ast] and one in [`rustc::hir`][hir].

[ast]: https://doc.rust-lang.org/nightly/nightly-rustc/syntax/ast/struct.StructField.html
[hir]: https://doc.rust-lang.org/nightly/nightly-rustc/rustc/hir/struct.StructField.html
