Remove some low-value `use` renamings.

There are a few common abbreviations like `use rustc_ast as ast` and
`use rust_hir as hir` for names that are used a lot. But there are also
some cases where a crate is renamed just once in the whole codebase, and
that ends up making things harder to read rather than easier. This
commit removes them.
