In coverage builds, avoid basic-block complexity in log_debug

Browse Source 
Ordinarily we skip calling log_fn(LOG_DEBUG,...) if debug logging is
completely disabled.  However, in coverage builds, this means that
we get spurious complaints about partially covered basic blocks, in
a way that makes our coverage determinism harder to check.
