Currently we have an inconsistency between the "input" and "no input" cases: - no input: `rustc --print=sysroot -Whelp` prints the lint help. - input: `rustc --print=sysroot -Whelp a.rs` prints the sysroot. It makes sense to print the lint help in both cases, because that's what happens with `--help`/`-Zhelp`/`-Chelp`. In fact, the `describe_lints` in the "input" case happens amazingly late, after *parsing*. This is because, with plugins, lints used to be registered much later, when the global context was created. But #117649 moved lint registration much earlier, during session construction. So this commit moves the `describe_lints` call to a single spot for both for both the "input" and "no input" cases, as early as possible. This is still not as early as `--help`/`-Zhelp`/`-Chelp`, because `-Whelp` must wait until the session is constructed. |

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.
