Turns out all six of these impls are incorrect.

This build is no longer a forked version with temporary bugfixes, everything
should be upstreamed!

Now that the final bug fixes have been merged into sccache we can start
leveraging sccache on the MSVC builders on AppVeyor instead of relying on the
ad-hoc caching strategy of trigger files and whatnot.

Some accesses in OperandPairs were missing. Fixes rust-lang#41479.

Fixes rust-lang#33287

We've got a freshly minted beta compiler, let's update to use that on nightly!
This has a few other changes associated with it as well

* A bump to the rustc version number (to 1.19.0)
* Movement of the `cargo` and `rls` submodules to their "proper" location in
  `src/tools/{cargo,rls}`. Now that Cargo workspaces support the `exclude`
  option this can work.
* Updates of the `cargo` and `rls` submodules to their master branches.
* Tweak to the `src/stage0.txt` format to be more amenable for Cargo version
  numbers. On the beta channel Cargo will bootstrap from a different version
  than rustc (e.g. the version numbers are different), so we need different
  configuration for this.
* Addition of `dev` as a readable key in the `src/stage0.txt` format. If present
  then stage0 compilers are downloaded from `dev-static.rust-lang.org` instead
  of `static.rust-lang.org`. This is added to accomodate our updated release
  process with Travis and AppVeyor.

Haiku: fix initial platform support

Step::replace_one should put a one, not a zero (Issue rust-lang#41492)

Turns out all six of the replace_* impls were backwards.

Address platform-specific behavior in TcpStream::shutdown

Fixes rust-lang#25164

r? @rust-lang/libs from the GitHub thread, it seems like documenting this behavior is okay, but I want to make sure that's what you want.

Invalid module location

Add missing OperandPair struct field index adjustments. Fixes rust-lang#41479.

This is a bug fix for a regression in rust-lang@6d841da.
