Remove AstJumpLabel (#6221)
Remove AstJumpLabel

AstJumpGo now references one if its enclosing AstJumpBlocks, and
branches straight after the referenced block.

That is:

```
JumpBlock a {
   ...
   JumpGo(a);
   ...
}
// <--- the JumpGo(a) goes here
```

This is sufficient for all use cases and makes control flow much easier to
reason about. As a result, V3Const can optimize a bit more aggressively.

Second half of, and fixes #6216

astgen: Enforce the use of aliased operand accessors (#4688)
This patch enforces the use of the most specific accessors for operands
which have an '@astgen alias' declaration, by making the superclass
accessors of the same operands private. This ensures client code is
cleaner as you can't use multiple different methods to reference the
same operands (which we used to in some places). Also prep for some
refactoring.

Geza Lore 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.
