Although it is always possible to destroy and recreate the design to
simulate a power-on reset, this has two drawbacks:
* Black boxes are also destroyed and recreated, which causes them
to reacquire their resources, which might be costly and/or erase
important state.
* Pointers into the design are invalidated and have to be acquired
again, which is costly and might be very inconvenient if they are
captured elsewhere (especially through the C API).

cxxrtl: run `hierarchy -auto-top` if no top module is present.
In most cases, a CXXRTL simulation would use a top module, either
because this module serves as an entry point to the CXXRTL C API,
or because the outputs of a top module are unbuffered, improving
performance. Taking this into account, the CXXRTL backend now runs
`hierarchy -auto-top` if there is no top module. For the few cases
where this behavior is unwanted, it now accepts a `-nohierarchy`
option.
