* also implicitly tests for the access of signals during simulation that are
not referenced in any statements

and could not be accessed in simulation

sim: keep track of unreferenced items
...
* items that are never referenced in any statements do not end up in the
namespace or in the verilog
* this memorizes items if they can not be found in the namespace and keeps
track of their values

fhdl/verilog: revert "fhdl/verilog: add simulation parameter to avoid simulation tricks in synthetizable code"

Revert "fhdl/verilog: do not use initial begin in _printinit (not accepted by all synthesis tools ex: Synplify Pro does not accept it)"
...
This breaks simulations, and we will try to use the "reg name = value" syntax instead.
