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.

This is a proper fix for the compiler warning. A termination condition is
...
not needed, as it can never be reached: an edge must exist.

the interface to SplitCriticalEdge so that it splits an edge if it is critical,
