fallofpheonix 5a93cdbc09 Remove useless -Zunpretty=identified option
Fixes #10671

The `-Zunpretty=identified` option (without `expanded`) is effectively
useless because `NodeId`s are unassigned prior to macro expansion,
leading them to just be `NodeId::MAX_AS_U32`.

This commit removes the `Identified` variant from `PpSourceMode` and
removes `-Zunpretty=identified` from the command-line options. Users
should use `-Zunpretty=expanded,identified` instead (which is retained)
if they want to inspect `NodeId`s.

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.
