Cary Coutant a1893a821c Silence GCC 9 error about deprecated implicit copy constructor. 
Replacing push_back() with emplace_back() eliminates the calls to the
copy constructor, but I still had to provide explicit copy constructors
because of the call to vector::reserve(), which tries to instantiate them
even though they'll never actually be called when reserve() is called
on an empty vector.

	emplace_back for GCC 5 and later.
	* incremental.h (Incremental_binary::Input_reader): Provide copy
	constructor.
