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.

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.
