Fix for br978 - assertion involving addition of $ivlh_to_unsigned() result.
...
$ivlh_to_unsigned, unlike $signed and $signed, can cause a reduction
in width. The shared PECallFunction::cast_to_width_ method did not
support this.

Fix for GitHub issue #62 - assertion failure on too many array/vector indices.

there are dimensions.

Fix handling of expression width with $ivlh_to_unsigned.

a self-determined width.

expression is signed.

Handle nil queue as a was to delete a queue.

Treat this like assigning null to a dynamic array. This deletes the
queue and thus has the effect of clearing it.

generator, and elaborate the arrays in the first place.

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.

Add support for dynamic array/queue "last" index ($)
...
Internally, treat the "$" as a special expression type that takes
as an argument the signal that is being indexed. In the vvp target,
use the $last system function to implement this.

This works by translating it to a $size() system function call.
The $size function is already implemented for dynamic queues and
it is easy enough to expand it for queues.
