Subzero: Improve class definition hygiene.

Subzero: Improve class definition hygiene.

Delete zero-argument ctor where possible.

Delete default copy ctor and default assignment operator where possible (some were missed in the past).

(The above are not done to the cross tests because we aren't yet building them with C++11.)

Declare single-argument ctor as "explicit".
