Update Rust toolchains and rustup

USAGE:
    rustup[EXE] update [OPTIONS] [toolchain]...

ARGS:
    <toolchain>...    Toolchain name, such as 'stable', 'nightly', or '1.8.0'. For more
                      information see `rustup help toolchain`

OPTIONS:
        --no-self-update    Don't perform self update when running the `rustup update` command
        --force             Force an update, even if some components are missing
        --force-non-host    Install toolchains that require an emulator. See
                            https://github.com/rust-lang/rustup/wiki/Non-host-toolchains
    -h, --help              Print help information

DISCUSSION:
    With no toolchain specified, the `update` command updates each of
    the installed toolchains from the official release channels, then
    updates rustup itself.

    If given a toolchain argument then `update` updates that
    toolchain, the same as `rustup toolchain install`.
