Class definitions may reference class types in containing scopes.
...
We need the scope where the class is defined so that it can find
types in that containing scope. Note that most definitions cannot
escape into the the lexical scope of the class, but some can.

Handle arrays of class objects.
...
This goes all the way down to the vvp level, where we create support
for arrays of objects, generate the new code in the -tvvp code
generator, and elaborate the arrays in the first place.

Partial fix for br956 (various enumeration bugs)

When looking for an enumeration look in the current scope and then
recursively in any parent scope.
Add enumeration definitions to a package scope.

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.
