Ensure that users cannot use generated arguments. 
This commit gensyms the generated ident for replacement arguments so
that users cannot refer to them. It also ensures that levenshtein
distance suggestions do not suggest gensymed identifiers.

Rollup merge of #60327 - matthewjasper:handle-local-outlives-lbl, r=nikomatsakis 
Search for incompatible universes in borrow errors

If we have a borrow that has to live for `'static` we need to check for
any regions in incompatible universes when trying to find the cause.

03122e1bac Auto merge of #60006 - nnethercote:json-for-pipelining, r=alexcrichton 
In JSON output, emit a directive after metadata is generated.

To implement pipelining, Cargo needs to know when metadata generation is
finished. This is done via a new JSON "directive".

Unfortunately, metadata file writing currently occurs very late during
compilation, so pipelining won't produce a speed-up. Moving metadata
file writing earlier will be a follow-up.

7bcb0cffb6 In JSON output, emit a directive after metadata is generated. 
To implement pipelining, Cargo needs to know when metadata generation is
finished. This commit adds code to do that. Unfortunately, metadata file
writing currently occurs very late during compilation, so pipelining
won't produce a speed-up. Moving metadata file writing earlier will be a
follow-up.

The change involves splitting the existing `Emitter::emit` method in
two: `Emitter::emit_diagnostic` and `Emitter::emit_directive`.

The JSON directives look like this:
```
{"directive":"metadata file written: liba.rmeta"}
```
The functionality is behind the `-Z emit-directives` option, and also
requires `--error-format=json`.

f007e6f442 Identify when a stmt could have been parsed as an expr 
There are some expressions that can be parsed as a statement without
a trailing semicolon depending on the context, which can lead to
confusing errors due to the same looking code being accepted in some
places and not others. Identify these cases and suggest enclosing in
parenthesis making the parse non-ambiguous without changing the
accepted grammar.
