1154: Initial support for lang items (and str completion) r=flodiebold a=marcogroppo
This PR adds partial support for lang items.
For now, the only supported lang items are the ones that target an impl block.
Lang items are now resolved during type inference - this means that `str` completion now works.
Fixes#1139.
(thanks Florian Diebold for the help!)

1138: Add L_DOLLAR and R_DOLLAR r=matklad a=edwin0cheng
As discussion in issue https://github.com/rust-analyzer/rust-analyzer/issues/1132 and PR #1125 , this PR add 2 `Syntax::Kind` : `L_DOLLAR` and `R_DOLLAR` for representing `Delimiter::None` in mbe and proc_marco. By design, It should not affect the final syntax tree, and will be discard in `TreeSink`.
My original idea is handling these 2 tokens case by case, but i found that they will appear in every place in the parser (imagine `tt` matcher). So this PR only handle it in `Parser::do_bump` and `Parser::start`, although It will not fix the `expr` matcher executing order problem in original idea.

1076: Const body inference r=flodiebold a=Lapz
This is the second part of #887. I've added type inference on const bodies and introduced the DefWithBody containing Function, Const and Static. I want to add tests but im unsure on how I would go about testing that completions work.

1081: Async closure syntax r=matklad a=robojumper
Fixes#1080.
Also fixes an error introduced by #1072 where something like `async move "foo"` in expression position would trigger the assertion in `block_expr`.

These are now used when parsing type bounds. In addition parsing paths inside a
bound now does not recursively parse paths, rather they are treated as separate
bounds, separated by +.
