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

- Set AlwaysBreakTemplateDeclarations to true

5b9806ae6d Improve V3Combine 
- Always use a fast function to replace a slow one if available
- Iterate to fixed point (i.e.: if combining made more functions
identical, combine those too). This will be more useful in the future.
- Use only single, const traversal

Rework Ast hashing to be stable (#2974) 
Rework Ast hashing to be stable

Eliminated reliance on pointer values in AstNode hashes in order to make
them stable. This requires moving the sameHash functions into a visitor,
as nodes pointed to via members (and not child nodes) need to be hashed
themselves.

The hashes are now stable (as far as I could test them), and the impact
on verilation time is small enough not to be reliably measurable.

Split V3Hashed to V3Hasher and V3DupFinder (#2967) 
V3Hasher is responsible for computing AstNode hashes, while V3DupFinder
can be used to find duplicate trees based on hashes. Interface of
V3DupFinder simplified somewhat. No functional change intended at this
point, but hash computation might differ in minor details, this however
should have no perceivable effect on output/runtime.

Implements (#2964)
