Log:
  Pull in r230058 from upstream llvm trunk (by Benjamin Kramer):

    LoopRotate: When reconstructing loop simplify form don't split edges
    from indirectbrs.

    Yet another chapter in the endless story. While this looks like we
    leave the loop in a non-canonical state this replicates the logic in
    LoopSimplify so it doesn't diverge from the canonical form in any way.

    http://llvm.org/PR21968

  This fixes a "Cannot split critical edge from IndirectBrInst" assertion
  failure when building the devel/radare2 port.

  PR:        195480, 196987
