First, both `AstPrinterSupport` and `HirPrinterSupport` have a `sess` method. This commit introduces a `Sess` trait and makes the support traits be subtraits of `Sess`, to avoid some duplication. Second, both support traits have a `pp_ann` method that isn't needed if we enable `trait_upcasting`. This commit removes those methods. (Both of these traits will be removed in a subsequent commit, as will the `trait_upcasting` use.) |

The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
