3632: ra_cargo_watch: log errors r=matklad a=Veetaha
Until this moment we totally ignored all the errors from cargo process. Though this is still true, but we
now try to log ones that are critical (i.e. misconfiguration errors and ignore compile errors).
This fixes#3631, and gives us a better error message to more gracefully handle the #3265
Though I think that outputting this only to `Output` channel is not enough. We should somehow warn the user that he passed wrong arguments to `cargo-watch.args`. I didn't bother looking for how to do this now, but this PR at least gives us something.

As stated by matklad, reading the stderr
should be done alngside with
stdout via select() (or I guess poll()),
there is no such implementation in stdlib,
since it is quite low level and platform-dependent and it
also requires quite a bit of unrelated code we don't use it for now.
As referenced by bjorn3, there is an implementation of the needed read2() function
in rustc compiletest. The better solution will be to extract this function
to a separate crate in future:

3672: gen_assists_docs skip hidden files r=JoshMcguigan a=JoshMcguigan
Fixes#3670
Skips hidden files when generating assist docs, which fixes an issue where the tests would fail while an editor has created a temp file in the assists directory.
There is similar logic [here](2720e2374b/xtask/tests/tidy-tests/main.rs (L157)), although in that case the `DirEntry` is a `walkdir::DirEntry` rather than a `fs::DirEntry`. Also, it's not immediately clear that it is worth moving this functionality to somewhere accessible from both of these places and creating dependencies in this way. Let me know if this is off the mark.

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
