08f8faedd0 syntax: Rename some keywords 
`CrateRoot` -> `PathRoot`, `::` doesn't necessarily mean crate root now
`SelfValue` -> `SelfLower`, `SelfType` -> `SelfUpper`, both `self` and `Self` can be used in type and value namespaces now

787959c20d Use Cow in Token::String. 
`Printer::word` takes a `&str` and converts it into a `String`, which
causes an allocation. But that allocation is rarely necessary, because
`&str` is almost always a `&'static str` or a `String` that won't be
used again.

This commit changes `Token::String` so it holds a `Cow<'static, str>`
instead of a `String`, which avoids a lot of allocations.

Rollup merge of #55384 - nnethercote:better-integer_lit-float_lit, r=michaelwoerister 
Avoid unnecessary allocations in `float_lit` and `integer_lit`.

This commit avoids an allocation when parsing any float and integer
literals that don't involved underscores.

This reduces the number of allocations done for the `tuple-stress`
benchmark by 10%, reducing its instruction count by just under 1%.
