Rick Altherr 3c48de8e21 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
iterations in the outer loop.

Rick Altherr 0265d7b100 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().
