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.

Delete AstNode user5 (#4638) 
This saves about 5% memory. V3AstUserAllocator is appropriate for most use
cases, performance is marginally up as we are mostly D-cache bound on
large designs.

Geza Lore 63c694f65f Streamline dump control options 
- Rename `--dump-treei` option to `--dumpi-tree`, which itself is now a
  special case of `--dumpi-<tag>` where tag can be a magic word, or a
  filename
- Control dumping via static `dump*()` functions, analogous to `debug()`
- Make dumping independent of the value of `debug()` (so dumping always
  works even without the debug flag)
- Add separate `--dumpi-graph` for dumping V3Graphs, which is again a
  special case of `--dumpi-<tag>`
- Alias `--dump-<tag>` to `--dumpi-<tag> 3` as before

internal documentation for details.

Geza Lore 0c70a0dcbf Remove redundant 'virtual' keywords from overridden methods 
'virtual' is redundant when 'override' is present, so keep only
'override'.

Add t/t_dist_cppstyle.pl to check for this.

Geza Lore 381c87a1eb Remove VN_CAST_CONST and VN_AS_CONST. 
The _CONST suffix on these macros is only lexical notation, pointer
constness can be preserved by overloading the underlying
implementations appropriately. Given that the compiler will catch
invalid const usage (trying to assign a non-const pointer to a const
pointer variable, etc.), and that the declarations of symbols should
make their constness obvious, I see no reason to keep the _CONST
flavours.

Geza Lore 2ebed755e6 V3Simulate: Avoid copying while managing free list. 
V3Simulate reuses allocated AstConst nodes for efficiency, however this
used to be implemented in a way that required a deep copy of a
std::unorderd_map<_, std::deque<_>>, which was quite inefficient when it
grew large. The free list is now managed without any copying. This takes
the V3Table pass from taking 12s to 0.2s on SweRV EH1.
