053a09529a Reduce ammount of errors given unclosed delimiter 
When in a file with a non-terminated item, catch the error and consume
the block instead of trying to recover it more granularly in order to
reduce the amount of unrelated errors that would be fixed after adding
the missing closing brace. Also point out the possible location of the
missing closing brace.

d673d0ac84 Use heuristics to recover parsing of missing ; 
- Detect `,` and `:` typos where `;` was intended.
- When the next token could have been the start of a new statement,
  detect a missing semicolon.

Clarify diagnostics when using `~` as a unary op

Rollup merge of #65455 - nnethercote:avoid-unnecessary-TokenTree-to-TokenStream-conversions, r=petrochenkov 
Avoid unnecessary `TokenTree` to `TokenStream` conversions

A `TokenStream` contains any number of `TokenTrees`. Therefore, a single `TokenTree` can be promoted to a `TokenStream`. But doing so costs two allocations: one for the single-element `Vec`, and one for the `Lrc`. (An `IsJoint` value also must be added; the default is `NonJoint`.)

The current code converts `TokenTree`s to `TokenStream`s unnecessarily in a few places. This PR removes some of these unnecessary conversions, both simplifying the code and speeding it up.

212ae58f36 Change Lit::tokens() to Lit::token_tree(). 
Because most of the call sites have an easier time working with a
`TokenTree` instead of a `TokenStream`.
