Float 'incomplete_features' out to a const for visibility
Float `let incomplete_features` out to a `const INCOMPLETE_FEATURES` and colocate near `active` features so that it is easier to find and edit.

rustc: Flag metadata compatible with multiple CGUs
It looks like the `OutputType::Metadata` kind in the compiler was
misclassified in #38571 long ago by accident as incompatible with
codegen units and a single output file. This means that if you emit both
a linkable artifact and metadata it silently turns off multiple codegen
units unintentionally!
This commit corrects the situation to ensure that if `--emit metadata`
is used it doesn't implicitly disable multiple codegen units. This will
ensure we don't accidentally regress compiler performance when striving
to implement pipelined compilation!
Document `Item` type in `std::env::SplitPaths` iterator.
Previously there wasn't any documentation to show what the type of
`Item` was inside `std::env::SplitPaths`. Now, in the same format as
other examples of docs in `std` for `Iterator#Item`, we mention the
type.
This fixes#59543.

Previously, we checked if the target of a projection type was itself an
inference variable. However, for Rustdoc rendering purposes, there's no
distinction between an inference variable ('_') and a type containing
one (e.g. (MyStruct<u8, _>)) - we don't want to render either of them.
Fixes#60269
Due to the complexity of the original bug, which spans three different
crates (hyper, tower-hyper, and tower), I have been unable to create a
minimized reproduction for the issue.
This renames `std::io::IoVec` to `std::io::IoSlice` and
`std::io::IoVecMut` to `std::io::IoSliceMut`, and stabilizes
`std::io::IoSlice`, `std::io::IoSliceMut`,
`std::io::Read::read_vectored`, and `std::io::Write::write_vectored`.
Closes#58452

Use "capacity" as parameter name in with_capacity() methods
See #60271.
The only place where I didn't change the parameter name is `RawVec`. The problem is that it has a `.cap()` method instead of the usual `.capacity()`:
597f432489/src/liballoc/raw_vec.rs (L200-L210)
Changing this would be a breaking change, and I guess that's not worth it.
But since I didn't change `.cap()` there, I didn't change the `cap` parameter name to `capacity`, either.
bootstrap: use correct version numbers for llvm-tools and lldb
The current URLs for the `llvm-tools` and `lldb` components are a bit broken right now:
```
https://static.rust-lang.org/dist/2019-04-25/llvm-tools-1.34.1 (fc50f328b 2019-04-24)-aarch64-unknown-linux-gnu.tar.gz
```
This PR uses proper version numbers for those. Tested a dist build locally and everything works.

Make "Implementations on Foreign Types" items in sidebar link to specific impls
This solves #56018 for most cases (though not work for foreign impls with same names)
Replace the `&'tcx List<Ty<'tcx>>` in `TyKind::Tuple` with `SubstsRef<'tcx>`
Part of the suggested refactoring for https://github.com/rust-lang/rust/issues/42340. As expected, this is a little messy, because there are many places that the components of tuples are expected to be types, rather than arbitrary kinds. However, it should open up the way for a refactoring of `TyS` itself.

rustc_metadata: more safely read/write the index positions.
This is a small part of a larger refactor, that I want to benchmark independently.
The final code would be even cleaner than this, so this is sort of an "worst case" test.
