Lars-Peter Clausen e7e663056a Handle invalid vector slice base expressions 
The elaboration of the base expression of a vector slice index can fail and
return a nullptr. Currently this results in a nullptr deref. Handle that
case by exiting the function early.

Lars-Peter Clausen 5be80046a9 Fix run_ivl.py 
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.

Marlon James d4aef1e6d8 Fix vpi_handle_by_name() handling of escaped identifiers when finding a toplevel module

without the leading '\' and trailing ' ', if there are any '.' characters,
the path will be broken up at the wrong point(s).

vvp is missing a parser rule for unsigned 2-state net arrays. E.g.

```
  bit a[0:1];
  assign a[0] = 1'b0;
```

will synthesize fine, but when running it with vvp cause a syntax error.

Lars-Peter Clausen 85bf2d11fa tgt-vvp: Cast reads from 2-state dynamic arrays/queues 
vvp does not track whether the values stored in a dynamic array or queue
are 2-state or 4-state. Internally the data is always stored as 4-state.

To make sure that the read value is actually 2-state do a cast for 2-state
reads.

E.g. performing an out-of-bounds access on a 2-state dynamic array or queue
will yield a undefined value.

Lars-Peter Clausen 560800489d tests: sv_queue_vec: Change base type to 4-state 
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.

Lars-Peter Clausen 0eb01fff1e vvp: Fix initial value propagation for 2-state non-automatic arrays 
For 2-state non-automatic arrays currently real 0.0 value is propagated as
the initial value. This will cause an assert at the downstream receivers
which expect a vector.

Make sure that the vector value 0 is propagated instead for 2-state
vectors.
