Most named constructs support a end label in SystemVerilog. The handling of
this end label is always the same.
* Generate an error if the end label does not match the name of the block
* Generate an error if not in SystemVerilog mode
* Delete the end label
Factor this into a common helper function. This reduces code size a bit and
results in consistent error messages.
The latter requires refreshing of some gold files to match the slightly
different error messages.

Check that invalid parameter overrides generate an error.
There are some cases that are not handled correctly today. The test will be
updated once they are addressed.

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.

Check that when an error message for a enum or struct data type is
generated it points to the location of the declaration of the type.

The test checks that all invalid declarations produce an error and also do
not crash the application.

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.
