4222: Introduce C/C++ for Visual Studio Code extension as an alternative debug engine for Debug Code lens. r=matklad a=vsrs
At the moment Debug Code Lens can use only one debug engine: lldb via [CodeLLDB](https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb) extension.
This PR adds support of the debug engine from the [MS C++ tools](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools) extension, as well as the configuration option. If both extensions are installed, `CodeLLDB` will be used by default.
Another new option `rust-analyzer.debug.sourceFileMap` allows, for example, to step into Rust std library during debugging. Works only with `MS C++ tools`.
On Windows:
```json
"rust-analyzer.debug.sourceFileMap": {
"/rustc/4fb7144ed159f94491249e86d5bbd033b5d60550": "${env:USERPROFILE}/.rustup/toolchains/stable-x86_64-pc-windows-msvc/lib/rustlib/src/rust"
}
```
On Linux:
```json
"rust-analyzer.debug.sourceFileMap": {
"/rustc/4fb7144ed159f94491249e86d5bbd033b5d60550": "~/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/src/rust"
}
```
4178: Validate the location of `crate` in paths r=matklad a=djrenren
**This solution does not fully handle `use` statements. See below**
This pull requests implements simple validation of usages of the `crate` keyword in `Path`s. Specifically it validates that:
- If a `PathSegment` is starts with the `crate` keyword, it is also the first segment of the `Path`
- All other usages of `crate` in `Path`s are considered errors.
This aligns with `rustc`'s rules. Unlike rustc this implementation does not issue a special error message in the case of `::crate` but it does catch the error.
Furthermore, this change does not cover all error cases. Specifically the following is not caught:
```rust
use foo::{crate}
```
This is because this check is context sensitive. From an AST perspective, `crate` is the root of the `Path`. Only by inspecting the full `UseItem` do we see that it is not in fact the root. This problem becomes worse because `UseTree`s are allowed to be arbitrarily nested:
```rust
use {crate, {{crate, foo::{crate}}}
```
So this is a hard problem to solve without essentially a breadth-first search. In a traditional compiler, I'd say this error is most easily found during the AST -> HIR conversion pass but within rust-analyzer I'm not sure where it belongs.
Under the implementation in this PR, such errors are ignored so we're *more correct* just not *entirely correct*.
4162: Complete assoc. items on type parameters r=jonas-schievink a=jonas-schievink
This is fairly messy and seems to leak a lot through the `ra_hir` abstraction (`TypeNs`, `AssocItemId`, ...), so I'd be glad for any advise for how to improve this.

This PR try to fix a deadlock in proc-macro srv by not unloading dlls.
Currently we load and unload dlls for each request, however rustc TLS is leaky , such that if we do it a lot of times, all TLS index will be consumed and it will be deadlocked inside panic (it is because panic itself is using TLS too).
4204: Use specific pattern when translating if-let-else to match r=matklad a=matklad
We *probably* should actually use the same machinery here, as we do
for fill match arms, but just special-casing options and results seems
to be a good first step.

4173: Use core instead of std for builtin derive macros r=edwin0cheng a=edwin0cheng
Fixed #4087.
We can't use `$crate` here right now because :
1. We have to able to detect `macro` 2.0 in collecting phase for finding `rustc_builtin_macro` attrs.
2. And we have to make hygiene works for builtin derive macro.
4159: For associated type shorthand (T::Item), use the substs from the where clause r=matklad a=flodiebold
So e.g. if we have `fn foo<T: SomeTrait<u32>>() -> T::Item`, we want to lower that to `<T as SomeTrait<u32>>::Item` and not `<T as SomeTrait<_>>::Item`.

4113: Support returning non-hierarchical symbols r=matklad a=kjeremy
If `hierarchicalDocumentSymbolSupport` is not true in the client capabilites
then it does not support the `DocumentSymbol[]` return type from the
`textDocument/documentSymbol` request and we must fall back to `SymbolInformation[]`.
This is one of the few requests that use the client capabilities to
differentiate between return types and could cause problems for clients.
See https://github.com/microsoft/language-server-protocol/pull/538#issuecomment-442510767 for more context.
