Explanation: This fixes a linker error when using
std::functionfrom Swift. In libc++std::functioninherits fromstd::__function::__func, which doesn't explicitly define a destructor but inherits fromstd::__function::__basewhich defines a virtual destructor.Scope: Changes IRGen of destructors of C++ structs.
Risk: Low, only affects C++ types.
Testing: Added a compiler test.
