To sum up what I have figured out, C++ transforms the coroutine "function" into
a trio of functions: a ramp function, an actor function, and a destruction
function. The ramp function acts as the actual

More data:
The coroutine actor is marked as artificial in
coro_build_actor_or_destroy_function. As a result, it is completely ignored by
gcov. In gcov's process_all_functions function, artificial

Using the better test case, I have determined that the coroutine _is_ being
instrumented with gcov counters. When disassembled, the output contains the
following in the bar() actor function:

I should be more explicit. The `std::cout` line in the example is just a
placeholder for "does some work here," and this example is specifically the
simplest version of a coroutine I could come up with
