3761: Append new match arms rather than replacing all of them r=matklad a=mattyhall
This means we now retain comments when filling in match arms. This fixes#3687. This is my first contribution so apologies if it needs a rethink! I think in particular the way I find the position to append to and remove_if_only_whitespace are a little hairy.

3727: Introduce ra_proc_macro r=matklad a=edwin0cheng
This PR implemented:
1. Reading dylib path of proc-macro crate from cargo check , similar to how `OUTDIR` is obtained.
2. Added a new crate `ra_proc_macro` and implement the foot-work for reading result from external proc-macro expander.
3. Added a struct `ProcMacroClient` , which will be responsible to the client side communication to the External process.

3707: Add ItemScope::visibility_of r=matklad a=edwin0cheng
~This PR implements `HasVisibility` for various constructs and change `Definition::search_scope` to use `Visibility` directly instead of depends on ad-hoc string parsing.~
This PR added `visibility_of` in `ItemScope` and `Module` and use it directly directly instead of depends on ad-hoc string parsing.
And also add a FIXME to indicate that there is a bug which do not search child-submodules in other files recursively in `Definition::search_scope`.
I will submit another PR to fix that bug after this is merged.

3700: fill match arms with empty block rather than unit tuple r=matklad a=JoshMcguigan
As requested by @Veetaha in #3689 and #3687, this modifies the fill match arms assist to create match arms as an empty block `{}` rather than a unit tuple `()`.
In one test I left one of the pre-existing match arms as a unit tuple, and added a body to another match arm, to demonstrate that the contents of existing match arms persist.

Sometimes my RA debugging workflow breaks because `.dbg` is applied to the variable that is used later in the code.
It's safer to consider the refences to avoid this for completions that may trigger the move.

3689: implement fill match arm assist for tuple of enums r=matklad a=JoshMcguigan
This updates the fill match arm assist to work in cases where the user is matching on a tuple of enums.
Note, for now this does not apply when some match arms exist (other than the trivial `_`), but I think this could be added in the future.
I think this also lays the groundwork for filling match arms when matching on tuples of non-enum values, for example a tuple of an enum and a boolean.

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:

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)

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

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.

It improves compile time in `--release` mode quite a bit, it doesn't
really slow things down and, conceptually, it seems closer to what we
want the physical architecture to look like (we don't want to
monomorphise EVERYTHING in a single leaf crate).
3573: Check all crates of the workspace r=matklad a=matklad
Previously, if the root of the was was a real crate, only this crate
was checked.
Ideally, we might want some kind of config here (which might be just
overriding the whole command), but `--workspace` is def a nicer
default.

3577: Protect against infinite macro expansion in def collector r=edwin0cheng a=flodiebold
Something I noticed while trying to make macro expansion more resilient against errors.
There was a test for this, but it wasn't actually working because the first recursive expansion failed. (The comma...)
Even with this limit, that test (when fixed) still takes some time to pass because of the exponential growth of the expansions, so I disabled it and added a different one without growth.
