Stephen Williams de215f1f8d Describe enum type to code generators 
This gets the enumeration type through to the ivl_target API so
that code generators can do something with it. Generate stub
output with tgt-stub, and generate the proper vvp run time to
make simple enumerations work from end to end.

Stephen Williams 5b5a6b05b7 Test type correctness during elaboration. 
Create a netenum_t class to carry the enumeration type in the
netlist.h structures, and use that type to check enumerations
with assignments.
