whitequark 6a29e1f5b7 write_verilog: write RTLIL::Sa aka - as Verilog ?.
Currently, the only ways (determined by grepping for regex \bSa\b) to
end up with RTLIL::Sa in a netlist is by reading a Verilog constant
with ? in it as a part of case, or by running certain FSM passes.
Both of these cases should be round-tripped back to ? in Verilog.
