Nicholas Nethercote 9b64d52d78 Reduce diagnostic type visibilities.
Most diagnostic types are only used within their own crate, and so have
a `pub(crate)` visibility. We have some diagnostic types that are
unnecessarily `pub`. This is bad because (a) information hiding, and (b)
if a `pub(crate)` type becomes unused the compiler will warn but it
won't warn for a `pub` type.

This commit eliminates unnecessary `pub` visibilities for some
diagnostic types, and also some related things due to knock-on effects.
(I found these types with some ad hoc use of `grep`.)

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.
