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.

2a7aa28b20 V3Simulate/V3Table: change deques to vectors for performance 
We can get away with only push_back and back on sequence containers, in
which case std::vector is significantly faster than std::deque.
