Chris Lattner a5b11705b6 Move SplitBlockPredecessors out of loopsimplify into BasicBlockUtils.h
as a global helper function.  At the same type, switch it from taking
a vector of predecessors to an arbitrary sequential input.  This allows
us to switch LoopSimplify to use a SmallVector for various temporary
vectors that it passed into SplitBlockPredecessors.
