c++: fix double free when a symbol_type was moved
Currently the following piece of code crashes (with parse.assert),
because we don't record that s was moved-from, and we invoke its dtor.
{
auto s = parser::make_INT (42);
auto s2 = std::move (s);
}
Reported by Wolfgang Thaller.

* data/c++.m4 (by_type): Provide a move-ctor.
(basic_symbol): Be sure not to read a moved-from value.
* tests/c++.at (C++ Variant-based Symbols Unit Tests): Check this case.
