3671: Add identity expansion checking in ill-form expansion r=flodiebold a=edwin0cheng
This PR try to add more checking code in error case in macro expansion. The bug in #3642 is introduced by #3580 , which allow ill-form macro expansion in *all* kind of macro expansions.
In general we should separate hypothetical macro expansion and the actual macro expansion call. However, currently the `Semantic` workflow we are using only support single macro expansion type, we might want to review it and make it works in both ways. (Maybe add a field in `MacroCallLoc` for differentiation)
Fix#3642

3668: disable invert-if assist for if-let r=matklad a=JoshMcguigan
Fixes#3281
This disables the invert-if assist for if-let expressions, fixing the bug reported in #3281.
While in the exact case reported in #3281, `if let Some(_) = foo { ...`, it would be possible to invert the if-let pattern, in most cases it will not be possible, so disabling this assist for if-let expressions seems reasonable.

3665: vscode: remove unnecessary code r=matklad a=Veetaha
This cancel is unnecessary since we cancel the previous inlay hints requests in `fetchHints()` method itself. This is not a hard error, we just called cancel() 2 times.

3623: 'Fill match arms' should work with existing match arms r=matklad a=slyngbaek
Addresses #3039
This essentially adds missing match arms. The algorithm for this
can get complicated rather quickly so bail in certain conditions
and rely on a PlaceholderPat.
The algorighm works as such:
- Iterate through the Enum Def Variants
- Attempt to see if the variant already exists as a match arm
- If yes, skip the enum variant. If no, include it.
- If it becomes complicated, rather than exhaustively deal with every
branch, mark it as a "partial match" and simply include the
placeholder.
Conditions for "complication":
- The match arm contains a match guard
- Any kind of nested destrucuring
Order the resulting merged match branches as such:
1. Provided match arms
2. Missing enum variant branch arms
3. End with Placeholder if required
- Add extra tests

3541: Completition for type name? #3418 r=matklad a=slyngbaek
Iterate through TupleStructPat's until a MatchArm if
one exists. Store in a new is_pat_bind_and_path bool
and allow the `complete_scope` to find matches.
Added some tests to ensure it works in simple and nested cases.

3656: Simplify arenas r=matklad a=matklad
At the moment, Arena is paranetrized by two types: index and data. The original motivation was to allow index to be defined in the downstream crate, so that you can add inherent impls to the index.
However, it seems like we've never actually used that capability, so perhaps we should switch to a generic Index impl? This PR tries this out, switching only `raw.rs` and parts of `hir_def`.
wdyt?

3629: Alternative aproach to plugin auto update r=matklad a=matklad
This is very much WIP (as in, I haven't run this once), but I like the result so far.
cc @Veetaha
The primary focus here on simplification:
* local simplification of data structures and control-flow: using union of strings instead of an enum, using unwrapped GitHub API responses
* global simplification of control flow: all logic is now in `main.ts`, implemented as linear functions without abstractions. This is stateful side-effective code, so arguments from [Carmack](http://number-none.com/blow/john_carmack_on_inlined_code.html) very much apply. We need all user interractions, all mutations, and all network requests to happen in a single file.
* as a side-effect of condensing everything to functions, we can get rid of various enums. The enums were basically a reified control flow:
```
enum E { A, B }
fn foo() -> E {
if cond { E::A } else { E::B }
}
fn bar(e: E) {
match e {
E::A => do_a(),
E::B => do_b(),
}
}
==>>
fn all() {
if cond { do_a() } else { do_b() }
}
```
* simplification of model: we don't need to reinstall on settings update, we can just ask the user to reload, we don't need to handle nightly=>stable fallback, we can ask the user to reinstall extension, (todo) we don't need to parse out the date from the version, we can use build id for nightly and for stable we can write the info directly into package.json.
