Rollup merge of #142687 - cjgillot:less-hir_crate, r=oli-obk
Reduce uses of `hir_crate`.

I tried rebasing my old incremental-HIR branch. This is a by-product, which is required if we want to get rid of `hir_crate` entirely.

The second commit is a drive-by cleanup. It can be pulled into its own PR.

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.
