…, r=compiler-errors Rid the AST & HIR pretty printer of cruft Found while working on rust-lang#119163. For `trait Trait: ?Sized {}` (semantically malformed), we currently output `trait Trait for ? Sized {}` (sic!) / `trait Trait for ? Sized { }` (sic!) if `-Zunpretty=expanded` / `-Zunpretty=hir` is passed. `trait Tr for Sized? {}` (rust-lang#15521) and later also `trait Tr for ?Sized {}` (I guess, rust-lang#20194) is former Rust syntax. Hence I'm removing these outdated branches. ~~This will conflict with rust-lang#119163, therefore marking this PR as blocked.~~ Rebased
