Jannis Harder 985f4926b7 verilog: Fix const eval of unbased unsized constants 
When the verilog frontend perfomed constant evaluation of unbased
unsized constants in a context-determined expression it did not properly
extend them by repeating the bit value. This only affected constant
evaluation and not constants that made it through unchanged to RTLIL.
The latter case was already covered by tests and working before.

This fixes the const-eval issue by checking the `is_unsized` flag in
bitsAsConst and extending the value accordingly.

The newly added test also tests the already working non-const-eval case
to highlight that both cases should behave the same.

Henner Zeller a3a8f7be38 Remove a statement without effect. 
The return value of the min(...) call is never used.
Looks like some leftover from some previous implementation.

Jannis Harder fb1c2be76b verilog: Support void functions 
The difference between void functions and tasks is that always_comb's
implicit sensitivity list behaves as if functions were inlined, but
ignores signals read only in tasks. This only matters for event based
simulation, and for synthesis we can treat a void function like a task.

Jannis Harder 390d1c583a verific: Fix enum_values support and signed attribute values 
This uses the same constant parsing for enum_values and for attributes
and extends it to handle signed values as those are used for enums that
implicitly use the int type.
