A method call needs to ignore a single NULL argument from the parser
...
The parser always passes a single NULL argument for system tasks. For a
method call which will add a signal to call the method on we need to
ignore this NULL argument.

Fix for GitHub issue #37 - bug in expression width pruning.
...
If an expression contains a division, remainder, or right shift operation,
set the expression min_width to UINT_MAX to flag that the expression width
cannot be pruned. Using UINT_MAX ensures that the min_width won't change
as we continue to elaborate the expression.
