 * milestone:   => 8.6.1


Comment:

 I'll definitely get something in for 8.6, whether auto-generated or hand-
 crafted. I've had some good hand-crafted pass sequences sitting around for
 a while now.

 Progress on the autotuner has stalled because (1) it finds weird bugs in
 LLVM sometimes, and I should just fix them instead of trying to avoid
 them, (2) I'll be working with some people this summer to create a proper
 autotuner for LLVM, so we can hopefully use that instead of what I hacked
 together.
