Instead of taking a fixed set of arguments, use variadics so that we can pass arbitrary arguments to the handler. This is the first step towards using the handler to handle other non-assertion-related failures, like std::unreachable and an exception being thrown in -fno-exceptions mode, which would improve user experience by including additional information in crashes (right now, we call abort() without additional information).
