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. gold/ * incremental.cc (Sized_incremental_binary::setup_readers): Use emplace_back for GCC 5 and later. * incremental.h (Incremental_binary::Input_reader): Provide copy constructor. (Sized_incremental_binary::Sized_input_reader): Likewise.
