This commit fixes a regression from rust-lang#44601 where lowering attribute to HIR now involves expanding interpolated tokens to their actual tokens. In that commit all interpolated tokens were surrounded with a `DelimToken::None` group of tokens, but this ended up causing regressions like rust-lang#44730 where the various attribute parsers in `syntax/attr.rs` weren't ready to cope with `DelimToken::None`. Instead of fixing the parser in `attr.rs` this commit instead opts to just avoid the `DelimToken::None` in the first place, ensuring that the token stream should look the same as it did before where possible. Closes rust-lang#44730
Based on ExpHP's comment in https://users.rust-lang.org/t/refcell-borrow-mut-get-strange-result/12994 > it would perhaps be nicer if it didn't put something that could be > misinterpreted as a valid string value The previous Debug implementation would show: RefCell { value: "<borrowed>" } The new one is: RefCell { value: <borrowed> }
…uietMisdreavus Add pub visibility for methods as well Fixes rust-lang#44527. r? @QuietMisdreavus
Expand size_of docs This PR does 3 things. 1. Adds a description of what pointer size means to the primitive pages for usize and isize. 2. Says the general size of things is not stable from compiler to compiler. 3. Adds a table of sizes of things that we do guarantee. As this is the first table in the libstd docs, I've included a picture of how that looks. 
…, r=arielb1 Remove str_eq lang item It's not really a lang item. Also remove outdated note. The reference uses this as an example so it has to be updated.
fix an incorrect assertion in the doc example for `std::io::copy` I think this wasn't caught by CI because the `foo` wrapper function was only defined and not called. This seems to be the norm for doc examples that define a `foo` function. Is that on purpose?
…lies-emitendregions, r=arielb1 Make `-Z borrowck-mir` imply that `EndRegion`'s should be emitted. Before this change, the `-Z borrowck-mir` flag is useless if you do not also pass `-Z emit-end-regions`. So, in the same spirit as f2892ad, make `-Z borrowck-mir` also emit `EndRegion` statements. (This will hopefully avoid some initial speed bumps for new-comers helping out with NLL.)

rustc: Don't use DelimToken::None if possible This commit fixes a regression from rust-lang#44601 where lowering attribute to HIR now involves expanding interpolated tokens to their actual tokens.

improve english in create_dir_all docs Just minor nitpicking.
Less confusing placeholder when RefCell is exclusively borrowed Based on ExpHP's comment in [*RefCell.borrow_mut get strange result*](https://users.rust-lang.org/t/refcell-borrow-mut-get-strange-result/12994): > it would perhaps be nicer if it didn't put something that could be misinterpreted as a valid string value The previous Debug implementation would show: RefCell { value: "<borrowed>" } The new one is: RefCell { value: <borrowed> }
