Noticed the two had converged so much they literally became equivalent. So one could go hehe

bab4ca914e Rollup merge of #138291 - jdonszelmann:optimize-attr, r=oli-obk 
rewrite `optimize` attribute to use new attribute parsing infrastructure

r? ```@oli-obk```

I'm afraid we'll get quite a few of these PRs in the future. If we get a lot of trivial changes I'll start merging multiple into one PR. They should be easy to review :)

Waiting on #138165 first

get more uses (statics, struct fields, etc.)

2cd2d24967 Remove MetaItemParser::{path,deconstruct}. 
They're equivalent, and `path` is unused, and `deconstruct` has only one
call site outside of `path`.

sentences.

2fef0a30ae Replace infallible name_or_empty methods with fallible name methods. 
I'm removing empty identifiers everywhere, because in practice they
always mean "no identifier" rather than "empty identifier". (An empty
identifier is impossible.) It's better to use `Option` to mean "no
identifier" because you then can't forget about the "no identifier"
possibility.

Some specifics:
- When testing an attribute for a single name, the commit uses the
  `has_name` method.
- When testing an attribute for multiple names, the commit uses the new
  `has_any_name` method.
- When using `match` on an attribute, the match arms now have `Some` on
  them.

In the tests, we now avoid printing empty identifiers by not printing
the identifier in the `error:` line at all, instead letting the carets
point out the problem.

4c0cbaeb9e Remove TokenStream::flattened and InvisibleOrigin::FlattenToken. 
They are no longer needed.

This does slightly worsen the error message for a single test, but that
test contains code that is so badly broken that I'm not worried about
it.

0b2d7062c4 Introduce sym::dummy and Ident::dummy. 
The idea is to identify cases of symbols/identifiers that are not
expected to be used. There isn't a perfectly sharp line between "dummy"
and "not dummy", but I think it's useful nonetheless.
