1. Eliminate piles of extra semicolons from expanded code …

   Look at `cargo rustc --profile=check -- -Zunpretty=expanded` of the
   following program:
   
       use quote::quote;
       fn main() {
           let _ = quote!(1 + 1);
       }
   
   Before:
   
       use quote::quote;
       fn main() {
           let _ =
               {
                   let mut _s = ::quote::__private::TokenStream::new();
                   ;
                   ;
                   ;
                   ::quote::__private::parse(&mut _s, "1");
                   ;
                   ::quote::__private::push_add(&mut _s);
                   ;
                   ::quote::__private::parse(&mut _s, "1");
                   ;
                   ;
                   ;
                   ;
                   _s
               };
       }
   
   After:
   
       use quote::quote;
       fn main() {
           let _ =
               {
                   let mut _s = ::quote::__private::TokenStream::new();
                   ::quote::__private::parse(&mut _s, "1");
                   ::quote::__private::push_add(&mut _s);
                   ::quote::__private::parse(&mut _s, "1");
                   _s
               };
       }
