rtlil: Improve performance of SigSpec::extract(SigSpec, SigSpec*)
Converting to a pool<SigBit> is fairly expensive due to inserts somewhat
frequently causing rehashing. Instead, walk through the pattern SigSpec
directly on a chunk-by-chunk basis and apply it to this SigSpec's
individual bits. Using chunks for the pattern minimizes the number of

rtlil: speed up SigSpec::sort_and_unify()
std::set<> internally is often a red-black tree which is fairly
expensive to create but fast to lookup. In the case of
sort_and_unify(), a set<> is constructed as a temporary object to
attempt to speed up lookups. Being a temporarily, however, the cost of
creation far outweights the lookup improvement and is a net performance
loss. Instead, sort the vector<> that already exists and then apply
std::unique().
