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!)

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.

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 +.
We allow invalid inner attributes to be parsed, e.g. inner attributes that are
not directly after the opening brace of the match block.
Instead we run validation on `MatchArmList` to allow better reporting of errors.
692: [WIP] Correctly parse attributes r=matklad a=DJMcNab
Reference - https://doc.rust-lang.org/reference/attributes.html
This fixes/investigates inner attributes for:
- [x] `impl` blocks
- [x] `extern` blocks
- [x] `fn`s (fixes#689)
- [x] `mod`s (already supported)
- [x] 'block expressions' (the long text just describes all 'blocks' used as statements)
This also investigates/fixes outer attributes for:
- [ ] 'most statements' (see also: #685, https://doc.rust-lang.org/reference/expressions.html#expression-attributes)
- [x] Enum variants, Struct and Union fields (Fixed in #507)
- [ ] 'Match expression arms' (@matklad can you provide a test case which explains what this means?)
- [ ] 'Generic lifetime or type parameters'
- [ ] 'Elements of array expressions, tuple expressions, call expressions, tuple-style struct and enum variant expressions'
- [ ] 'The tail expression of block expressions'
