Problem ScheduleDAG on PowerPC, X86 works fine.
Long story short: https://llvm.org/bugs/show_bug.cgi?id=31890
The backend fails to schedule a given DAG, the reason being that there is
an instruction and it glue that needs to be broken apart as they can't be
scheduled consecutively. See attached file for a picture of the DAG.
Not sure what's the best course of action is, and not sure why this isn't a
problem for the X86 backend
