Fix to commit coroutines immediately on wait statements (#4229) 
Event-triggered coroutines live in two stages: 'uncommitted' and 'ready'. First
they land in 'uncommitted', meaning they can't be resumed yet. Only after
coroutines from the 'ready' queue are resumed, the 'uncommitted' ones are moved
to the 'ready' queue, and can be resumed. This is to avoid self-triggering in
situations like waiting for an event immediately after triggering it.

However, there is an issue with `wait` statements. If you have a `wait(b)`, it's
being translated into a loop that awaits a change in `b` as long as `b` is
false. If `b` is false at first, the coroutine is put into the `uncommitted`
queue. If `b` is set to true before it's committed, the coroutine won't get
resumed.

This patch fixes that by immediately committing event controls created from
`wait` statements. That means the coroutine from the example above will get
resumed from now on.

0e769d42a1 Optimize trigger evaluation 
Pack the elements of VlTriggerVec as dense bits (instead of a 1 byte
bool per bit), and check whether they are set on a word granularity.
This effectively transforms conditions of the form `if (trig.at(0) |
trig.at(2) | trig.at(64))` into `if (trig.word(0) & 0x5 | trig.word(1) &
0x1)`. This improves OpenTitan ST by about 1%, worth more on some other
designs.

Fix C++ compile errors when passing class refs as task arg (#4063) 
1. Fixes passing a null reference as a task argument. Before this patch it would
   cause a C++ compile error like `cannot convert ‘VlNull’ to ‘VlClassRef<...>’`.

2. Fixes passing a class reference as a task argument when the argument is a
   reference to a base class. Before the patch it would cause a C++ compile
   error like `cannot convert ‘VlClassRef<{DERIVED_CLASS}>’ to ‘VlClassRef<{BASE_CLASS}>`.
