Subject: [PATCH v2 3/3] [RFC] Generic Red-Black Trees

I've put a few performance notes in comments.  Specifically, I'm curious
if an inline function that expands to 128+ bytes like this should
possibly be wrapped in an __attribute__((flatten))
__attribute__((noinline)) function to force full expansion in one place
and then prevent it from getting inlined elsewhere (to keep the
generated code size down).
