3536: Add get and set for `Env` r=matklad a=edwin0cheng
This PR add three things :
1. Add `get` and `set` in `Env`.
2. Implement fixture meta for `with_single_file`.
3. Add `env` meta in fixture.

3513: Completion in macros r=matklad a=flodiebold
I experimented a bit with completion in macros. It's kind of working, but there are a lot of rough edges.
- I'm trying to expand the macro call with the inserted fake token. This requires some hacky additions on the HIR level to be able to do "hypothetical" expansions. There should probably be a nicer API for this, if we want to do it this way. I'm not sure whether it's worth it, because we still can't do a lot if the original macro call didn't expand in nearly the same way. E.g. if we have something like `println!("", x<|>)` the expansions will look the same and everything is fine; but in that case we could maybe have achieved the same result in a simpler way. If we have something like `m!(<|>)` where `m!()` doesn't even expand or expands to something very different, we don't really know what to do anyway.
- Relatedly, there are a lot of cases where this doesn't work because either the original call or the hypothetical call doesn't expand. E.g. if we have `m!(x.<|>)` the original token tree doesn't parse as an expression; if we have `m!(match x { <|> })` the hypothetical token tree doesn't parse. It would be nice if we could have better error recovery in these cases.

3516: Handle visibility in more cases in completion r=matklad a=flodiebold
This means we don't show private items when completing paths or method calls.
We might want to show private items if we can edit their definition and provide a "make public" assist, but I feel like we'd need better sorting of completion items for that, so they can be not shown or sorted to the bottom by default. Until then, they're usually more of a distraction to me.

3518: Add parse_to_token_tree r=matklad a=edwin0cheng
This PR introduce a function for parsing `&str` to `tt::TokenTree`:
```rust
// Convert a string to a `TokenTree`
pub fn parse_to_token_tree(text: &str) -> Option<(tt::Subtree, TokenMap)> {
````

Allow trait autocompletions for unimplemented associated fn's, types,
and consts without using explicit keywords before hand (fn, type,
const).
The sequel to #3108.
3499: Resolve `Self::AssocTy` in impls r=matklad a=flodiebold
To do this we need to carry around the original resolution a bit, because `Self`
gets resolved to the actual type immediately, but you're not allowed to write
the equivalent type in a projection. (I tried just comparing the projection base
type with the impl self type, but that seemed too dirty.) This is basically how
rustc does it as well.
Fixes#3249.

3482: Fix regression from #3451 r=matklad a=edwin0cheng
There is a regression from #3451 such that the following code has failed to parse in raw item collecting phase:
```rust
macro_rules! with_std {
($($i:item)*) => ($(#[cfg(feature = "std")]$i)*)
}
with_std! {
mod macros;
mod others;
}
```
### Rationale
We always assume the last token of an statement will not end with a whitespace, which is true. It is because in parsing phase, we always emit `SyntaxNode` before any whitespace. Such that in various parts of RA code, we solely check the semi-colon by using `SyntaxNode::last_child_token() == ";"` .
However, in #3451, we insert some whitespaces between puncts such that we broke above assumption. This PR fixed this bug by make sure we don't add any whitespace if it is a semicolon.

Note that `detail` was replced with `function_signature` to avoid
calling `from` on FunctionSignature twice.
I didn't add new tests because the current ones seem enough.
3429: Fix panic on eager expansion r=matklad a=edwin0cheng
When lazy expanding inside an eager macro, its *parent* file of that lazy macro call must be already exists such that a panic is occurred because that parent file is the eager macro we are processing.
This PR fix this bug by store the argument syntax node as another eager macro id for that purpose.
Personally I don't know if it is a good answer for this bug.

3392: Implement concat eager macro r=matklad a=edwin0cheng
This PR implements the following things:
1. Add basic eager macro infrastructure by introducing `EagerCallId` such that the new `MacroCallId` is defined as :
```
#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash)]
pub enum MacroCallId {
LazyMacro(LazyMacroId),
EagerMacro(EagerMacroId),
}
```
2. Add `concat!` builtin macro.

3385: Fix#3373 r=matklad a=flodiebold
Basically, we need to allow variables in the caller self type to unify with the
impl's declared self type. That requires some more contortions in the variable
handling. I'm looking forward to (hopefully) handling this in a cleaner way when
we switch to Chalk's types and unification code.

3387: Type inference for slice patterns r=flodiebold a=JoshMcguigan
Fixes#3043
Notes to reviewer:
1. This only works if `expected` is `Ty::Apply`. I'm not sure of the implications of this.
1. This only works if the slice pattern only has a prefix. I think this means it doesn't work for subslice patterns, which are currently only available behind a feature flag.
