Zalathar 93f69b2300 Don't skip argument parsing when running rustc with no arguments
Setting up the argument parser to parse no arguments is a tiny bit of wasted
work, but avoids an otherwise-unnecessary special case.

In particular, this lets us avoid having to deal with multiple different APIs
to determine whether the compiler is nightly or not.

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.
