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.

Reduce peak memory use of V3Subst (#4687)
V3Subst is currently the pass responsible for peak memory usage. This
patch saves ~16% of peak memory on OpenTitan.

2 changes:
- It is actually safe to delete the substituted expressions immediately,
  but this is the lesser contribution
- More importantly, we only ever substitute STMTTEMP variables, which
  are always defined within the same CFunc, so we can limit the scope of
  the optimization to CFunc. This allows us to reclaim the SubstVarEntry
  structures at the end of every CFunc, rather than at the end of the
  whole pass, which gives us most of the memory savings.

Generated output is identical

Wilson Snyder 761adf1cf0 Internals: Add cloneTreePure to prepare for side effect check.
Use cloneTreePure when what is being cloned must be side-effect free.
Use cloneTree when safe to contain side effects (e.g. cloning module).

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

Geza Lore 38a8d7fb2e Remove redundant 'inline' keywords from definitions

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.
