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.

Rollup merge of #65552 - JohnTitor:use-bitwise-not, r=Dylan-DPC 
Clarify diagnostics when using `~` as a unary op

It seems we prefer `bitwise not` to `bitwise negation`.
Fixes #57239

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`.
