Suggest assoc type on type not found in trait method definition
Given
```
trait A {
type Bla;
fn to_bla(&self) -> Bla;
}
```
suggest using `Self::Bla`:
```
error[E0412]: cannot find type `Bla` in this scope
--> file.rs:3:25
|
LL | fn to_bla(&self) -> Bla;
| ^^^ help: try: `Self::Bla`
```
Fix#62650.
Update mdbook, cargo, books
This updates the last of the books using mdbook 0.1, finally removing it from the build. Cargo, the reference, and the rustc book were the last to change. This should have a noticeable impact on CI times.
I decided to remove the version switcher from the rustbook tool. It seemed a little awkward keeping it with one version. If we ever need it in the future, we can always add it back, it is a relatively small amount of code. I would just like to avoid the temptation to split the versions in the future.

Update to LLVM 9 trunk
Following the preparatory changes in #62474, this updates the LLVM submodule to https://github.com/rust-lang/llvm-project/tree/rustc/9.0-2019-07-12 and:
* Changes the LLVM Rust bindings to account for the new SubtargetSubTypeKV.
* Adjusts a codegen test for the new form of the byval attribute that takes a type.
* Makes a PGO codegen test more liberal with regard to order and linkage.
* Builds InstrProfilingPlatformWindows.c as part of libprofiler_builtins.
* Moves registration of additional passes (in particular sanitizers) to the end of the module pass manager.
* Disables LLDB on builders.

port rust for vxWorks
The supporting for vxWorks has been enabled in this branch. Although there are still a lots of work to do, I would like to upstream the code and fix the problems later.
Please let me know if there is anything I have to do before upstream the code.

Thanks,

ci: Remove Travis/AppVeyor configuration
Now that we've fully moved to Azure Pipelines and bors has been updated
to only gate on Azure this commit removes the remaining Travis/AppVeyor
support contained in this repository. Most of the deletions here are
related to producing better output on Travis by folding certain
sections. This isn't supported by Azure so there's no need to keep it
around, and if Azure ever adds support we can always add it back!

Actually call `visit_block_entry` in `DataflowResultsConsumer`
This fixes a trivial bug in `DataflowResultsConsumer`: `visit_block_entry` is never called when visiting dataflow results.
A previous version of #62547 used this API and included this fix, but it has since switched to `DataflowResultsCursor` making this commit irrelevant.
Fix#62660
If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE.
Fixes#62660.
Make VaListImpl<'f> invariant over the 'f lifetime
After doing some research on variance and going back to look at `VaList` and `VaListImpl`, I realized that `VaList<'a, 'f>` is invariant over the `'f` lifetime (and covariant over `'a`), but `VaListImpl<'f>` isn't invariant but probably should be. This patch makes `VaListImpl<'f>` invariant over `'f`.

Less unsafe in the array example of MaybeUninit docs
I believe this is an acceptable way to initialize elements of `[MaybeUninit<T>; _]` arrays. Miri agrees. Conceptually, we are working at the array level, above the `MaybeUninit`, and as we are replacing it wholesale, this should pose no problem to soundness. And the code is easier to read.

Remove never_type feature requirement for exhaustive patterns
I **think** this resolves#51221
At least for me, it doesn't ICE anymore and all tests are still passing, so LGTM

Update stdsimd to stdarch
The stdsimd repository no longer lives in `rust-lang-nursery/stdsimd` but now lives in `rust-lang/stdarch` instead. This PR updates the stdsimd submodule to the stdarch master branch.
