Hosted compiler docs outdated

[bjorn3]

The compiler docs hosted on docs.rust-lang.org seem to be outdated with respect to the latest available nightly.

The docs will be updated when a new nightly is released, which requires a working RLS first. RLS has recently been fixed by #50379, so I'd expect an update within a day.

The compiler docs has been updated to Version 1.27.0-nightly (8a37c75a3 2018-05-02). Thus closing.
