[BasicBlockUtils] Allow critical edge splitting with callbr terminators

After D129205, we support SplitBlockPredecessors() for predecessors
with callbr terminators. This means that it is now also safe to
invoke critical edge splitting for an edge coming from a callbr
terminator. Remove checks in various passes that were protecting
against that.
