[TableGen] Replace two SmallDenseSets with SmallSets.
The key here is HwMode indices. They're going to be small numbers,
contiguous, and only a few different values. I don't think we need
to go through the SmallDenseSet hashing.
A BitVector would be even better, but we don't have the upper
bound here.
