Akira Hatanaka 4ce0e5a892 [CodeGen] Do not push a destructor cleanup for a struct that doesn't ...

have a non-trivial destructor.

This fixes a bug introduced in r328731 where CodeGen emits calls to
synthesized destructors for non-trivial C structs in C++ mode when the
struct passed to EmitCallArg doesn't have a non-trivial destructor.
Under Microsoft's ABI, ASTContext::isParamDestroyedInCallee currently
always returns true, so it's necessary to check whether the struct has a
non-trivial destructor before pushing a cleanup in EmitCallArg.

This fixes PR37146.
