Thanks for looking at the code! I could, but I think that doesn't
really add much benefit (llvm-readobj dumping is already tested, as
you noticed).

I'd prefer to implement support in llvm-objdump (it needs it anyway)
and enable these tests properly as part of that. I'm probably going to
do that later this afternoon, I'm really just making a first-pass
minimising diffs that crept in with our internal branch during the
initial commits at the moment.

Cheers.

Tim.
