463df6720c Fix wrong handling of bare dyn Trait exposed by canonicalizer fix 
The self type in the `dyn Trait` trait ref should always be ^0, but we didn't
put that in there in the bare case.

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).

Fixes #1618.

Merge #3169 
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`.

e14e7ffa34 Fix coercion of &T to itself 
The autoderef coercion logic did not handle matching placeholders. This led to
some type mismatches.

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.
