std::vector and llvm::SmallVector have annoying performance
tradeoffs. No, I don't expect this to matter, and now it won't.

Provide dbgs(), a circular-buffering debug output stream. By default it

simply passes output to errs(). If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it. This is handy when debugging very large inputs.
