Geza Lore 8681861be9 Improve bitop tree optimization 
- Remove redundant casting
- Cheaper final XOR parity flip (~/^1 instead of != 0)
- Support XOR reduction of ~XOR nodes
- Don't add redundant masking of terms
- Support unmasked terms
- Add cheaper implementation for single bit only terms
- Ensure result is clean under all circumstances (this fixes current bugs)

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.
