libstdc++: Initialize all subobjects of std::function
The std::function::swap member swaps each data member unconditionally,
resulting in -Wmaybe-uninitialized warnings for a default constructed
object. This happens because the _M_invoker and _M_functor members are
only initialized if the function has a target.
This change ensures that all subobjects are zero-initialized on
construction.

libstdc++-v3/ChangeLog:
* include/bits/std_function.h (_Function_base): Add
default member initializers and define constructor as defaulted.
(function::_M_invoker): Add default member initializer.
