  1. Derive std::mem::ManuallyDrop from Clone and Copy. 

    Although types that don't implement Drop can't be Copyable, this can
still be useful when ManuallyDrop is used inside a generic type. This
doesn't derive from Copy as that would require T: Copy + Clone, instead
it provides an impl of Clone for T: Clone.

  2. Additional traits for std::mem::ManuallyDrop 

    Add pass-through implementations for all of the derivable traits. These
cannot be derived since ManuallyDrop is a union.
