This removes the regress-msys2.list file, fixes the output from the
pr2509349a.v test to not be different on different systems, and
documents the $readmempath task.
This file contained some SystemVerilog tests that are not yet supported.
Move the tests to the regress-vvp.list format, and mark them as NI so
that we know what's going on.
The pr1002 test has a always block with the `dataout` in its sensitivity
list. It compares `dataout` to `expected_dataout`.
Both `dataout` and `expected_dataout` depend on `datain` and are updated in
the same cycle. This means there is no guarantee in which order they are
updated and the always block might get scheduled before `expected_dataout`
has been updated. This can lead to a test failure.
To avoid this slightly change the test to use a task to perform the
comparison and add an explicit delay before the task is executed so that
all updates have a chance to be fully resolved

The first evaluation of an `assign` statement is scheduled at the same time as
`initial` statements.
There are some test cases that evaluate the result of an `assign` statement
in an `initial` statement. This is an inherent race condition and might
fail depending on the exact order of evaluation.
To fix this add an additional delay in the `initial` block. This will make
sure that all `assign` statements get fully resolved first.

To escape the `.` in the regex it needs to be prefixed with a `\`. But
since the `\` is a escape character in python strings it needs to be
escaped as well.
Without this some versions of python print the following warning:
run_ivl.py:36: SyntaxWarning: invalid escape sequence '\.'
match= re.search(b'Icarus Verilog version ([0-9]+)\.([0-9]+)', text)

Starting with commit 96df251c95 ("Suppress unnecessary VCD/LXT/LXT2
warnings about packages.") there is no longer a warning printed that the
unit scope can't be printed if it is empty.
Remove the special SystemVerilog mode gold file for the pr1963962 test that
expects this warning.

Check that reversed part selects result in an error. Check this for both

Commit 56c5bf1da1 ("ivtest: Remove regress v11, v12, and v13") removed the
`expected_fail` argument from the `check_run_outputs()` function, but did
not remove all references. This causes the run_ivl.py script to fail. The
script is part of the CI pipeline and causes all PRs to fail.
Remove the remaining references to `expected_fail` to make it work again.

Now that out-of-bounds access on 2-state queues and dynamic arrays yields
the right value move the tests from the "Not Implemented" list to the list
of tests that get run.

The sv_queue_vec test uses queues of 2-state vectors, but also checks if
certain operations on the queue yield 'X.
2-state queues should never yield 'X and the test only passes because of a
bug. In preparation for fixing the bug change the test to use a 4-state
base type instead.

Check that it is possible to declare module ports with only partial
attributes. Other attributes should be inherited from the previous port in
the list or use the default.

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.

Some tests require a specific compiler error, rather than just failing. Add
support for this by allowing to check for gold files for CE tests.

Implicit named port connections are only supported by SystemVerilog. Add a
check to generate an error when trying to use it in Verilog mode.
Regression test br_gh315 is modified to run in SystemVerilog mode since it
makes use of implicit named port connections.
