auto merge of #9320 : chris-morgan/rust/unreachable-macro-part-two-of-two-containing-the-destruction-of-the-unreachable-function, r=alexcrichton

This is the second of two parts of #8991, now possible as a new snapshot
has been made. (The first part implemented the unreachable!() macro; it
was #8992, 6b7b8f2682.)

``std::util::unreachable()`` is removed summarily; any code which used
it should now use the ``unreachable!()`` macro.

Closes #9312.

Closes #8991.
