Applied @efriedma's suggestions, changed the testcase to a MIR test which only runs the arm-cp-islands pass on it, making the test much less fragile.

To make MIR work properly for thumb(2), I had to move metadata about the target flags from ARMInstrInfo to ARMBaseInstrInfo. I can commit that part in a separate commit if you prefer that.
