Jim, it looks like this is the slowest running test in the entire
regression test suite now... it runs for over 30s on my system, where the
total lit runtime is 52 seconds =/

Is there any way to prune it down to a smaller test? Or maybe there is some
N^2 aspect to this?

The time appears to go to llvm-mc rather than macho-dump, but I've not
really dug into why. I just wanted to let you know.
