3905: add ellipsis field to hir pat record r=matklad a=JoshMcguigan
This PR corrects a `fixme`, adding an `ellipsis` field to the hir `Pat::Record` type. It will also be unlock some useful follow on work for #3894.
Additionally it adds a diagnostic for missing fields in record patterns.
~~Marking as a draft because I don't have any tests, and a small amount of manual testing on my branch from #3894 suggests it might *not* be working. Any thoughts on how I can best test this, or else pointers on where I might be going wrong?~~

Chalk now panics if we don't implement these methods and run with CHALK_DEBUG,
so I thought I'd try to implement them 'properly'. Sadly, it seems impossible to
do without transmuting lifetimes somewhere. The problem is that we need a `&dyn
HirDatabase` to get names etc., which we can't just put into TLS. I thought I
could just use `scoped-tls`, but that doesn't support references to unsized
types. So I put the `&dyn` into another struct and put the reference to *that*
into the TLS, but I have to transmute the lifetime to 'static for that to work.

3901: Add more heuristics for hiding obvious param hints r=matklad a=IceSentry
This will now hide `value`, `pat`, `rhs` and `other`. These words were selected from the std because they are used in commonly used functions with only a single param and are obvious by their use.
It will also hide the hint if the passed param **starts** or end with the param_name. Maybe we could also split on '_' and check if one of the string is the param_name.
I think it would be good to also hide `bytes` if the type is `[u8; n]` but I'm not sure how to get the param type signature.
Closes #3900

I think this makes is more clear which things are : AstNode and which
are : AstToken

I haven't actually profiled this, but not allocating a hash map (or
anything, really) seems like a good idea

We used to parse it as T: Fn() -> (u8 + Send), which is different from
the rustc behavior of T: (Fn() -> u8) + Send

- Adds a new AstElement trait that is implemented by all generated
node, token and enum structs
- Overhauls the code generators to code-generate all tokens, and
also enhances enums to support including tokens, node, and nested
enums

3880: Add support for attributes for struct fields r=matklad a=bnjjj
Hello I try to solve this example:
```rust
struct MyStruct {
my_val: usize,
#[cfg(feature = "foo")]
bar: bool,
}
impl MyStruct {
#[cfg(feature = "foo")]
pub(crate) fn new(my_val: usize, bar: bool) -> Self {
Self { my_val, bar }
}
#[cfg(not(feature = "foo"))]
pub(crate) fn new(my_val: usize, _bar: bool) -> Self {
Self { my_val }
}
}
```
Here is a draft PR to try to solve this issue. In fact for now when i have this kind of example, rust-analyzer tells me that my second Self {} miss the bar field. Which is a bug.
I have some difficulties to add this features. Here in my draft I share my work about adding attributes support on struct field data. But I'm stuck when I have to fetch attributes from parent expressions. I don't really know how to do that. For the first iteration I just want to solve my issue without solving on all different expressions. And then after I will try to implement that on different kind of expression. I think I have to fetch my FunctionId and then I will be able to find attributes with myFunction.attrs() But I don't know if it's the right way.
@matklad (or anyone else) if you can help me it would be great :D
