Unfortunately, this was not discovered earlier as swift-ide-test is not invoking the SIL passes that produce this diagnostic. When creating Swift spans from C++ spans we have no lifetime dependency information to propagate as C++ spans are modeled as escapable types. Hence, this PR introduces a helper function to bypass the lifetime checks triggered by this discepancy. Hopefully, the new utility will go away as the lifetime analysis matures on the Swift side and we get standardized way to deal with unsafe lifetimes.
