var EnableDetailedTracing = os.Getenv("LOTUS_VM_ENABLE_TRACING") == "1"

EnableDetailedTracing has different behaviour in the LegacyVM and FVM. In the LegacyVM, it enables detailed gas tracing, slowing down execution. In the FVM, it enables execution traces, which are primarily used to observe subcalls.
