As it is right now, there is only one worker available in the `rust-lang-libs`
AppVeyor project and there are other repos as well that we share this worker
with. This has been a problem for us because we sometimes hit a bors timeout if there
are too many builds queued up.
To improve the situation, I think we could try to use AppVeyor a bit less
often. The average PR is not going to break windows related things anyway, so
it should be fine to run it on r+/try/master only.
Ignore non-const ctor expressions in or_fn_call
Fixes https://github.com/rust-lang/rust-clippy/issues/1338
Should have been fixed by #919, however that focuses on const ctor expressions only, and `.or(Some(local))` isn't const.
This also automatically ignores things like `.or(Some(local.clone())` which we don't actually want to do; I need to figure out what to do here.

compiletest: Disambiguate extern crate deps shared with the compiler
Fixes#4015.
changelog: Handle deps shared with the compiler in the internal compiletest suite
Attempts to fix the multiple matching crates error using the `--extern dep=path` disambiguation. This only includes `serde` at the moment because it's the only problematic dep right now (is inside Rust sysroot and pulled via `extern crate` in the test suite).
I'm not exactly sure this is the right approach (FWIW it fixes the issue locally), please do tell if this should be done differently.
Allow allowing of toplevel_ref_arg lint
I'm not sure why some lints need the `HirId` to be able to recognize the
lint level attributes, but this commit makes the lint level attributes
work for `toplevel_ref_arg`.
Fixes#2332

Fix false positive in module_name_repetitions lint
This lint was triggering on modules inside expanded attrs, like
for example `#[cfg(test)]` and possibly more.
It was not reporting a location in #3892 because `span.lo()` and `span.hi()` both were 0.
Fixes#3892

Add Lint PathBufPushOverwrite
Closes#3923
This is a very simple Lint that checks if push is being called with a Root Path. Because that can make it overwrite the previous path.
I used std::path::Path to check if it's root, in order to keep it working across windows/linux environments instead of checking for '/'. Is that alright?
On the `if_chain!` block, Is there a way to make it short while getting the value of the first argument? I got the example from other lints.
Note that this is first Lint, I hope I got everything covered 🚀
Add run-rustfix for option_map_or_none lint

Change naive_bytecount applicability to MaybeIncorrect
We can't use `MachineApplicable` here as applying the fix will cause
another error because `bytecount` would first have to be added to the
Cargo.toml.
Example:
```
error: You appear to be counting bytes the naive way
--> $DIR/bytecount.rs:5:13
|
LL | let _ = x.iter().filter(|&&a| a == 0).count(); // naive byte count
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: Consider using the bytecount crate: `bytecount::count(x, 0)`
```
Just replacing it with the suggestion is not enough.
