Robert Baruch 7c50b89b24 Adds is_wire to SigBit and SigChunk 
Useful for PYOSYS because Python can't easily check wire against NULL.

Zachary Snow b6af90fe20 verilog: fix sizing of constant args for tasks/functions 
- Simplify synthetic localparams for normal calls to update their width
    - This step was inadvertently removed alongside `added_mod_children`
- Support redeclaration of constant function arguments
    - `eval_const_function` never correctly handled this, but the issue
      was not exposed in the existing tests until the recent change to
      always attempt constant function evaluation when all-const args
      are used
- Check asserts in const_arg_loop and const_func tests
- Add coverage for width mismatch error cases

Zachary Snow 220cb1f7bb verilog: error on macro invocations with missing argument lists 
This would previously complain about an undefined internal macro if the
unapplied macro had not already been used. If it had, it would
incorrectly use the arguments from the previous invocation.

Zachary Snow 8de2e863af verilog: support recursive functions using ternary expressions 
This adds a mechanism for marking certain portions of elaboration as
occurring within unevaluated ternary branches. To enable elaboration of
the overall ternary, this also adds width detection for these
unelaborated function calls.
