I'm having trouble writing a .mir file containing an INLINEASM_BR instruction because the verifier complains: `Bad machine code: MBB has unexpected successors which are not branch targets, fallthrough, EHPads, or inlineasm_br targets.`

It seems like whatever flag gets set on an MBB to say it is an inlineasm_br target does not get serialised in textual MIR. @jyknight does that sound right? Any suggestions for writing MIR test cases?
