[PATCH] D30480: [CodeGen] Add a basic MachineInstr unittest. NFC.

David pointed out the lack of tests in r296007, which adds another mode to MI::print().

I'm not entirely convinced it's valuable, but I figured I'd give it a shot.  I was wondering just how much effort it would take to write an MI test (turns out, a lot.)

So, this tests adds enough machinery to translate one MI from MIR (+IR), and uses that to test the 3 variants of print().

When (if) we merge MIR and MI dump, these tests should really just be replaced with our existing llc mir tests.
