Geza Lore e4f210eb38 Optimize Dfg algorithms with an open addressing hash table (#8307) 
This patch introduces V3HashTable.h, which defines an open addressing,
linear probing hash table. The table implement the public V3HashSet and
V3HashMap templates, which are generic containers. The benefit of this
over std::unordered_map and std::unordered_set is far better memory
locality during lookup. (The STL containers use chaining and require a
new heap allocation for every insertion, similarly probing involves
pointer chasing on collisions).

The new data structure is use in V3DfgCache, and V3DfgCse and yields a
significant speed improvement of those passes on large designs.

Geza Lore d04647f459 Fix library method argument references (#8252) 
Each VCMethod now carries a signature describing the access required of
the references passed as arguments to the call. 'r' if the argument is
read, 'w' if it is fully assigned so the old value does not matter, 'm'
if it is modified (or only conditionally assigned), with a trailing '+'
repeating the preceding entry for all remaining arguments.  Signatures
are validated at compile time, and V3Broken checks the arguments of
every AstCMethodHard against them.

The incorrect references this found and that are easy to fix are
repaired in this patch. "TODO" marks method that are currently broken or
not yet fit the scheme, these will be fixed in follow up patches.

Also renames SCHED_COMMIT and SCHED_ENQUEUE to NBA_COMMIT and
NBA_ENQUEUE, and remove unused methods.
