04b80a5f5d Drop length from Token::String 
It was always set to the string's length

5879146392 Rename pretty_print_* to scan_* to follow naming in the paper 
This is also easier to understand because the scan and print "tasks" are
separate, but previously were both called "print" or "pretty print."

4783d9eaa5 Remove is_begin/is_end functions from PrintState 
These are somewhat ambiguous (beginning/end of what?) so it's better to
inline their one use into the code.

57cf7a2e57 Simplify print_end 
Presumably the code was from an older age of Rust and can now be written
much simpler.

00ca508608 Move pp::Printer out field to owned String 
This enforces that eof() must be called to get the String out, and
generally is better from an API perspective. No users of pretty printing
pre-allocate the buffer.

e0ffa7c3d2 Inline State::new_from_input in pprust 
This function took too many arguments and are simple on the inside;
inlining them makes complexity go down.

hir::print's copy is unfortunately used from librustc_driver so inlining
it is not as straightforward.

Remove `ast::Guard`

With the introduction of `ast::ExprKind::Let` in https://github.com/rust-lang/rust/pull/60861, the `ast::Guard` structure is now redundant in terms of representing [`if let` guards](https://github.com/rust-lang/rust/issues/51114) in AST since it can be represented by `ExprKind::Let` syntactically. Therefore, we remove `ast::Guard` here.

However, we keep `hir::Guard` because the semantic representation is a different matter and this story is more unclear right now (might involve `goto 'arm` in HIR or something...).
