8048: Fix missing unresolved macro diagnostic in function body r=edwin0cheng a=brandondong

This was an issue I found while working on https://github.com/rust-analyzer/rust-analyzer/pull/7970.

**Reproduction:**
1. Call a non-existent macro in a function body.
```
fn main() {
  foo!();
}
```
2. No diagnostics are raised. An unresolved-macro-call diagnostic is expected.
3. If the macro call is instead outside of the function body, this works as expected.

I believe this worked previously and regressed in https://github.com/rust-analyzer/rust-analyzer/pull/7805.

**Behavior prior to https://github.com/rust-analyzer/rust-analyzer/pull/7805:**
- The unresolved-macro-call diagnostic did not exist. Instead, a macro-error diagnostic would be raised with the text "could not resolve macro [path]".
- This was implemented by adding an error to the error sink (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8L657).
- The error was propagated through 1a82af3527/crates/hir_def/src/body.rs (L123) eventually reaching 1a82af3527/crates/hir_def/src/body/lower.rs (L569).

**Behavior after:**
- Instead of writing to the error sink, an UnresolvedMacro error is now returned (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R631).
- The parent caller throws away the error as its function signature is `Option<MacroCallId>` (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R604).
- We instead now reach the warn condition (1a82af3527/crates/hir_def/src/body.rs (L124)) and no diagnostics are created in 1a82af3527/crates/hir_def/src/body/lower.rs (L575).

**Fix:**
- Make sure to propagate the UnresolvedMacro error. Report the error using the new unresolved-macro-call diagnostic.

7900: show function params in completion detail r=matklad a=JoshMcguigan

This resolves #7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes.

Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail?

edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big 👍 to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field.

8036: completions: provide relevance bonus for enum types, and suggest ref matches for fn and enum r=matklad a=JoshMcguigan

This PR makes several improvements to completions and completion sorting:

1. Provide exact match type relevance score bonus for enum variants
2. Suggest `&Foo` (ref_match) for enums if that is an exact type match
3. Suggest `&foo()` (ref_match) if `foo` returns a type which would be an exact match either with the reference or due to a `Deref` impl

### Before

![pre-ref-relevance-centralized](https://user-images.githubusercontent.com/22216761/111189377-3f05a580-8573-11eb-89be-58a45cb7f829.png)

### After

### Caveats

I think generic types will require some kind of fancier logic when testing for `exact_type_match`, so for now `Option`/`Result`/etc unfortunately still don't have great completions.

### Implementation

I implemented this in a way that I think makes it most likely for each completion type to be handled consistently. Just replace `CompletionItem::new` with `CompletionItem::new_with_type_info` and `exact_type_match`/`exact_name_match`/`ref_match` are all handled for you, in a way which is sure to be consistent across completion types. 

This approach does introduce some coupling/plumbing that didn't exist before. Notice for example `set_is_local` on the builder, because `set_relevance` was removed from the builder to enforce that the relevance was built "properly" with `CompletionItem::new_with_type_info`. But I think there are benefits to this approach, like `CompletionRelevance` should probably consider deprecation status, and we already tell the builder about that, so in the (likely near term) future we can just pass that information along to `CompletionRelevance` when the user calls `set_deprecated` rather than the user having to manually set it in two places. This basically just hides `CompletionRelevance` from the individual completions, so they only worry about the `CompletionItem` interface. At the moment this seems like a cleaner approach to me, but I'm open to feedback here. 

edit - I've reimplemented this in a simpler way, per feedback below.

7970: Fix incorrect diagnostics for failing built in macros r=jonas-schievink a=brandondong

**Reproduction:**
1. Use a built in macro in such a way that rust-analyzer fails to expand it. For example:

**lib.rs**
```
include!("<valid file but without a .rs extension so it is not indexed by rust-analyzer>");
```
2. rust-analyzer highlights the macro call and says the macro itself cannot be resolved even though include! is in the standard library (unresolved-macro-call diagnostic).
3. No macro-error diagnostic is raised.

**Root cause for incorrect unresolved-macro-call diagnostic:**
1. collector:collect_macro_call is able to resolve include! in legacy scope but the expansion fails. Therefore, it's pushed into unexpanded_macros to be retried with module scope.
2. include! fails at the resolution step in collector:resolve_macros now that it's using module scope. Therefore, it's retained in unexpanded_macros.
3. Finally, collector:finish tries resolving the remaining unexpanded macros but only with module scope. include! again fails at the resolution step so a diagnostic is created.

**Root cause for missing macro-error diagnostic:**
1. In collector:resolve_macros, directive.legacy is None since eager expansion failed in collector:collect_macro_call. The macro_call_as_call_id fails to resolve since we're retrying in module scope. Therefore, collect_macro_expansion is not called for the macro and no macro-error diagnostic is generated.

**Fix:**
- In collector:collect_macro_call, do not add failing built-in macros to the unexpanded_macros list and immediately raise the macro-error diagnostic. This is in contrast to lazy macros which are resolved in collector::resolve_macros and later expanded in collect_macro_expansion where a macro-error diagnostic may be raised.

The methods are being sorted by `coc` by closeness in file.

### After

Notice `bbb()` on top (type + name match), followed by `ddd()` (type match).

by allowing it to be invoked on references of names, now showing all (trait)
implementations of the given type in all crates instead of just the defining
crate as well as including support for builtin types

Example screenshot of `impl`s of Box in `log`, `alloc`, `std` and the current crate. Before you had to invoke it on the definition where it would only show the `impls` in `alloc`.

8027: Completion context remove exact match method in favor of fields r=JoshMcguigan a=JoshMcguigan

This is a minor cleanup PR following #8008. It removes the `expected_name_and_type` method on completion context in favor of using the fields. 

I thought this method was used in more places, or else it may have just made sense to make this change directly in #8008 🤷

8008: Completion context expected type r=matklad a=JoshMcguigan

Currently there are two ways completions use to determine the expected type. There is the `expected_type` field on the `CompletionContext`, as well as the `expected_name_and_type` method on the `RenderContext`. These two things returned slightly different results, and their results were only valid if you had pre-checked some (undocumented) invariants. A simple combination of the two approaches doesn't work because they are both too willing to go far up the syntax tree to find something that fits what they are looking for.

This PR makes the following changes:

1. Updates the algorithm that sets `expected_type` on `CompletionContext`
2. Adds `expected_name` field to `CompletionContext`
3. Re-writes the `expected_name_and_type` method to simply return the underlying fields from `CompletionContext` (I'd like to save actually removing this method for a follow up PR just to keep the scope of the changes down)
4. Adds unit tests for the `expected_type`/`expected_name` fields

All the existing unit tests still pass (unmodified), but this new algorithm certainly has some gaps (although I believe all the `FIXME` introduced in this PR are also flaws in the current code). I wanted to stop here and get some feedback though - is this approach fundamentally sound?

8018: Make Ty wrap TyKind in an Arc r=flodiebold a=flodiebold

... to further move towards Chalk.

This is a bit of a slowdown (218ginstr vs 213ginstr for inference on RA), even though it allows us to unwrap the Substs in `TyKind::Ref` etc..
