Commit 6887202 added the Self: Sized bound to the next_token function in the libsyntax::parse::lexer::Reader trait (diff here).
This bound doesn't seem necessary (it compiles fine without it), but it prevents using this method from a trait object.

Is there any reason for its addition? If not, could we remove it?

That must be a leftover from me trying to make unwrap_or_abort take a closure somehow work.. sorry.

I'm marking this as E-easy because all that needs to be done is to remove Self: Sized from here, I believe.

The bound is not required for compiling but it prevents using `next_token()` from a trait object.

Fixes rust-lang#33506.
