Handle dev-dependency cycles
cc https://github.com/rust-lang/rust-analyzer/issues/14167
This should fix cycles errors mostly (it fixes the one on rome/tools at least, but not on rustc. Though there it might just be because of rustc workspace being rustc workspace). Unfortunately this will effectively duplicate all crates currently, since if we want to be completely correct we'd need to set the test cfg for all dev dependencies and the transitive dependencies of those, something I worry we should try to avoid.
fix: Fix pat fragment handling in 2021 edition
Fixes https://github.com/rust-lang/rust-analyzer/issues/9055
The fix isn't that great, but we are kind of forced to do it the quick and hacky way right now since std has changed the `matches` macro to make use of this now. And for a proper fix we need to track hygiene for identifiers which is a long way off anyways
Register obligations during path inference
Fixes#14635
When we infer path expressions that resolve to some generic item, we need to consider their generic bounds. For example, when we resolve a path `Into::into` to `fn into<?0, ?1>` (note that `?0` is the self type of trait ref), we should register an obligation `?0: Into<?1>` or else their relationship would be lost.
Relevant part in rustc is [`add_required_obligations_with_code()`] that's called in [`instantiate_value_path()`].
[`instantiate_value_path()`]: 3462f79e94/compiler/rustc_hir_typeck/src/fn_ctxt/_impl.rs (L1052)
[`add_required_obligations_with_code()`]: 3462f79e94/compiler/rustc_hir_typeck/src/fn_ctxt/_impl.rs (L1411)
Specify `--pre-release` when publishing vsce nightly
According to https://code.visualstudio.com/api/working-with-extensions/publishing-extension#prerelease-extensions, when publishing pre-release versions, `--pre-release` must also be passed in the publish step.
Currently the behavior with and without the flag seems to be the same, but since it's documented to be required, don't rely on this staying that way.
This flag was previously removed in #13020, so this partially reverts that change.

doc(alias)-based completion round 2
Follow-up on #14433
We can now complete fields, functions and some use/mods.
Flyimports don't behave, I don't really have the time to understand the structure there either.
While reading the flyimport code, I removed one method only used there, the closure-tree was a bit confusing, I can revert that if you want.
Add syntax::make::ty_alias
There was until now no function that returns TypeAlias. This commit introduces a func that is fully compliant with the Rust Reference. I had problems working with Ident so for now the function uses simple string manipulation until ast_from_text function is called. I am however open to any ideas that could replace ident param in such a way that it accepts syntax::ast::Ident
fix: Resolve `$crate` in derive paths
Paths in derive meta item list may contain any kind of paths, including those that start with `$crate` generated by macros. We need to take hygiene into account when we lower paths in the list.
This issue was identified while investigating #14607, though this patch doesn't fix the broken trait resolution.
mbe: fix token conversion for doc comments
fixes#14611
when creating token trees for the converted doc comment, we should use the correct span in all places, rather than allowing some to remain unspecified. otherwise, things behave incorrectly.
Simple fix for make::impl_trait
This is my first PR in this project. I made this PR because I needed this function to work properly for the main PR I am working on (#14386). This is a small amendment to what it was before. We still need to improve this in order for it to fully comply with its syntactic definition as stated [here](https://doc.rust-lang.org/reference/items/implementations.html).
