  -----------
  [llvm-reduce] Use DenseSet instead of std::set (NFC).

When reducing functions with very large basic blocks (~ almost 1 million
BBs), the majority of time is spent maintaining the order in the std::set
for the basic blocks to keep.

In those cases, DenseSet<> is much more efficient. Use it instead.
