Check that non-blocking event control assignments works on an array part
select if the part select index is not an immediate value.
This is a copy of the nb_ec_array_pv test, but using variable indices
instead of immediate values.

Check that module ports can have the shortreal data type.
Note that SystemVerilog does not allow nets to be of shortreal type.
Supporting net ports with a shortreal type is a Icarus extension.

Overriding a parameter that does not exist will only generate a warning at
the moment. This can hide programming mistakes such as an typo in a
parameter override.
There is nothing in the LRMs to support that this should only be warning,
so elevate this to an error. This is consistent with how an error is
generated when trying to reference a non-existing port or variable.
The generated error message differentiates between whether the parameter
does not exist at all, or whether it is a localparam.
There are two regression tests that rely on that only a warning is
generated, these have been updated to expect an error.

Update the enum cast test to reflect that enum casts are now supported.
Also add a small check to verify that the right value got assigned to the
enum after the cast.

By adding ivtest to the iverilog source tree, it is easier to keep
the regression test synchronized with the source that is being tested.
This should be especially helpful for PRs that add a new feature, and
have a matching ivtest PR with the regression test for that feature.
