  1. Add Rvalue::AddressOf to MIR 

    This operator creates a raw pointer to a Place directly, without first
creating a reference. See RFC rust-lang#2582 for motivation.

The Rvalue is currently unused.

  2. Start generating AddressOf rvalues in MIR 

    `hir::BorrowKind::Raw` borrows and casting a reference to a raw
pointer no longer do a reborrow followed by a cast. Instead we
dereference and take the address.
