Martin Whitaker ab688613cc 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.

Martin Whitaker 301a7e587b Fix for GitHub issue #62 - assertion failure on too many array/vector indices.
Provide an error message for invalid code that contains more indices than
there are dimensions.

Martin Whitaker 22d15f9ca9 Fix handling of expression width with $ivlh_to_unsigned.
The first argument to $ivlh_to_unsigned should be treated as having
a self-determined width.

Cary R 96472e5537 For a signed R-value we can use the full width when converting to long
When trying to get the value we can use the full width of a long if the
expression is signed.

Stephen Williams d1a35d5152 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.

Stephen Williams dec4cd5071 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.

Martin Whitaker e5f49baaac 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.

Stephen Williams c9ff48bd4e 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.

Stephen Williams da63ef02d4 Implement the size method for queues.
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.

Martin Whitaker e82bafcb84 Fix for GitHub issue #30 : failed assertion in eval_tree.cc
The root cause was the constant propagation done during elaboration
of a multiply operation, which didn't check for mixed real/logic
expressions.

Cary R 81947edaa5 A bit select is not the same as selecting part of a packed array
When adding the ability to select part of a multi-dimensional packed
array the sign and size information for a true bit select was broken.

Stephen Williams 40b36337e2 Fix some bugs with packed array dimensions.
The netparray_t::slice_dimensions bug was the most insidious and
caused all manner of confusion. Also fix some other packed array
and unpacked array (and mixed) indexing calculations.
