Thanks for the .mir suggestions!

I had originally tried some of those, but llc choked.
I reduced the test a bit more, again limited by llc.

When I removed chunks of instructions from uninteresting blocks, either llc choked
or the problem did not reproduce.  So I'll leave that code in.  Perhaps more reduction
is feasible, but this test size seems reasonable.
