991: Use Marker argument for item parsers r=matklad a=pcpthm
Before doing this for expressions, I found that the pattern (Marker argument) should be applied to the item parsers because visiblity and modifiers are parsed in a separate function.
Fixed some parser bugs:
- Fix pub_expr: `pub 42;` was allowed.
- Fix incorrect parsing of crate::path: incorrectly parsed as `crate` as a visibility.

989: Implement naive version of fill_struct_fields assist r=matklad a=yanchith
Fixes#964
This implements the `fill_struct_fields` assist. Currently only works for named struct fields, but not for tuple structs, because we seem to be missing a `TupleStructLit` (akin to `StructLit`, but for tuple structs). I am happy to implement `TupleStructLit` parsing given some guidance (provided it's really missing) and make the assist work for tuple structs as well. Could do so either in this PR, or another one 🙂
Sorry if I missed something important, this is my first PR for Rust Analyzer.
Btw is there any way to run the assists in emacs?
UPDATE: I just realized that parsing `TupleStructLit` would be quite difficult as it it really similar, if not identical to a function call...

987: Refactor maybe_item to use Marker argument r=pcpthm a=pcpthm
As suggested at <https://github.com/rust-analyzer/rust-analyzer/pull/980#issuecomment-473659745>.
For expression paring functions, changing signature
- from `fn(&mut Parser) -> Option<CompletedMarker>` to `fn(&mut Parser, Marker) -> Result<CompletedMarker, Marker>`
- from `fn(&mut Parser) -> CompletedMarker` to `fn(&mut Parser, Marker) -> CompletedMarker`
is my plan.

983: support remainder assignment operator r=matklad a=JeanMertz
`%=` was returning errors for me, turns out it wasn't added as a valid assignment operation.
I'm not sure what the best location would be to add a test for this. Please let me know and I'll add one.

Asymptotically computing a set difference is faster but in the average
case we won't have more than ~10 functions. Also prefer not using hash
sets as these may yield nondeterministic results.
Implement `BindingMode` for pattern matching, so that types can be
correctly inferred using match ergonomics. The binding mode defaults to
`Move` (referred to as 'BindingMode::BindByValue` in rustc), and is
updated by automatic dereferencing of the value being matched.
