Use $ivl_unsigned to implement VHDL to_unsigned function.
...
The VHDL to_unsigned function with to arguments is best handled
in the ivl elaborator, so have it generate an $ivlh_to_unsigned
function call in the vhdlpp code, and implement it in the ivl
core.
Also, implement the 'length attribute as a $bits() call for
similar reasons.

Handle out-of range and undefined LHS word indices in assignments.
...
For constant word indices, issue a warning if the index is out of
range or an undefined value. In any case, the RHS value should be
discarded, and the actual assignment should be skipped.

Implement class constructors.
...
Class constructors are the "new" method in a class description.
Elaborate the constructor as an ordinary method, but the only
way to access this method is to implicitly call it. The elaborator
will take the constructor call and generate a naked "new" expression
and implicit constructor method call with the object itself as the
return value.

Handle error case of zero width in indexed part select.
...
The compiler doesn't currently check that the width of an indexed
part select is non-zero. If code contains this erroneous case, the
compiler can crash (with an assertion failure). This patch causes
the compiler to output a suitable error message and recover. It
also fixes a potential crash if an illegal expresson is encountered.
