336a3c6121 Fix #3373
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.

e313efb992 Do array unsizing for method receivers
It turns out rustc actually only unsizes array method receivers, so we don't
need to do any trait solving for this (at least for now).

Fixes #2670.

5fe220b987 Fix a common false-positive type mismatch
E.g. for `&{ some_string() }` in a context where a `&str` is expected, we
reported a mismatch inside the block. The problem is that we're passing an
expectation of `str` down, but the expectation is more of a hint in this case.
There's a long comment in rustc about this, which I just copied.

Also, fix reported location for type mismatches in macros.

f1f45f9191 Fix handling of const patterns
E.g. in `match x { None => ... }`, `None` is a path pattern (resolving to the
option variant), not a binding. To determine this, we need to try to resolve the
name during lowering. This isn't too hard since we already need to resolve names
for macro expansion anyway (though maybe a bit hacky).

3169: Show record field names in Enum completion r=flodiebold a=adamrk

Adresses https://github.com/rust-analyzer/rust-analyzer/issues/2947.
Previously the details shown when autocompleting an Enum variant would look like the variant was a tuple even if it was a record:
![2020-02-16-15:59:32_crop](https://user-images.githubusercontent.com/16367467/74607233-64f21980-50d7-11ea-99db-e973e29c71d7.png)

This change will show the names of the fields for a record and use curly braces instead of parentheses:
![2020-02-16-15:33:00_crop](https://user-images.githubusercontent.com/16367467/74607251-8ce17d00-50d7-11ea-9d4d-38d198a4aec0.png)

This required exposing the type `adt::StructKind` from `ra_hir` and adding a function 
```
kind(self, db: &impl HirDatabase) -> StructKind
```
in the `impl` of `EnumVariant`. 

There was also a previously existing function `is_unit(self, db: &impl HirDatabase) -> bool` for `EnumVariant` which I removed because it seemed redundant after adding `kind`.

3484d727c3 Extend analysis-stats a bit
This adds some tools helpful when debugging nondeterminism in analysis-stats:
 - a `--randomize` option that analyses everything in random order
 - a `-vv` option that prints even more detail

Also add a debug log if Chalk fuel is exhausted (which would be a source of
nondeterminism, but didn't happen in my tests).

I found one source of nondeterminism (rust-lang/chalk#331), but there are still
other cases remaining.

9dc1826cfa Fix various names, e.g. Iterator not resolving in core prelude
Basically, `Iterator` is re-exported via several steps, which happened to not be
resolved yet when we got to the prelude import, but since the name resolved to
the reexport from `core::iter` (just to no actual items), we gave up trying to
resolve it further.

Maybe part of the problem is that we can have
`PartialResolvedImport::Unresolved` or `PartialResolvedImport::Indeterminate`
with `None` in all namespaces, and handle them differently.

Fixes #2683.

67240c8d91 Fix #2705
The `-` turned into a `+` during a refactoring.

The original issue was caused by `Read` resolving wrongly to a trait without
type parameters instead of a struct with one parameter; this only fixes the
crash, not the wrong resolution.

2661: Implement infer await from async function r=flodiebold a=edwin0cheng

This PR is my attempt for trying to add support for infer `.await` expression from an `async` function, by desugaring its return type to `Impl Future<Output=RetType>`.

Note that I don't know it is supposed to desugaring it in that phase, if it is not suitable in current design, just feel free to reject it :)

2592: Add std::ops::Index support for infering r=edwin0cheng a=edwin0cheng

see also #2534

Seem like this can't fix #2534 for this case:

```rust
fn foo3(bar: [usize; 2]) {
    let baz = bar[1];   // <--- baz is still unknown ?
    println!("{}", baz);
}
```

6e1c2d0df8 Handle impl Trait more correctly
When calling a function, argument-position impl Trait is transparent; same for
return-position impl Trait when inside the function. So in these cases, we need
to represent that type not by `Ty::Opaque`, but by a type variable that can be
unified with whatever flows into there.

2466: Handle partial resolve cases r=matklad a=edwin0cheng

Another try to fix #2443 :

We resolve all imports every time in `DefCollector::collect` loop even it is resolved previously.  
This is because other unresolved imports and macros will bring in another `PerNs`, so we can only assume that it has been partially resolved.

2484: DynMap r=matklad a=matklad

Implement a `DynMap` a semi-dynamic, semi-static map, which helps to thread heterogeneously typed info in a uniform way. Totally inspired by df3bee3038/compiler/frontend/src/org/jetbrains/kotlin/resolve/BindingContext.java. 

@flodiebold wdyt? Seems like a potentially useful pattern for various source-map-like things.

f86fe3d891 Don't unify within a reference
If we are expecting a `&Foo` and get a `&something`, when checking the
`something`, we are *expecting* a `Foo`, but we shouldn't try to unify whatever
we get with that expectation, because it could actually be a `&Foo`, and `&&Foo`
coerces to `&Foo`. So this fixes quite a few false type mismatches.
