The module_output_port_list_def declares a output port with an implicit
data type and assigns an initial value to it. Since output ports with an
implicit data type are nets this test is not standard compliant.
This only works because at the moment the parser incorrectly flags all
output ports with an initial value as variables rather than following the
method defined by the standard to decide whether the port should be a net
or variable.
Make the test standard compliant by using an explicit data type for the
output port, in which case it will be a variable.

Check support for using the return statement in a task.
* That it is possible to exit form a task using the `return` statement
without affecting other concurrently running instances of the same task
* That it is possible to use return in a named block in a task
* That using a return value in a task results in a elaboration error
* Returning from inside a parallel block in a task results in a
elaboration error

Add a regression test to show that the proper dumpfile is selected, by
noting in the output from the vvp command what file name it is creating.
To make this work, I also needed to add some capabilities to the vvp_reg.py
regression test rig.
Check that struct assignment patterns with only positional arguments are
supported. Also check that invalid assignment patterns for structs report
an error.

This is a test for github issue#800. This should work on all platforms,
but Windows seems weird. The issue seems to be with Windows comparing
gold files with CR-LF weirdly, so make all the tests internal.
Add additional enum compatibility tests that check for compatibility in
different contexts.
* Array element
* Function return value
* Function and task argument
* struct member
* class property

Check that function calls with empty arguments are supported. Check the
general case and special cases such as calling a function with empty
arguments as part of a module port binding or force statements in automatic
contexts.
Also check that calling a function with too many trailing empty arguments
as well as passing an empty argument for a port without a default value is
an error.
