[Polly] Reject reject regions entered by an indirectbr/callbr. SplitBlockPredecessors is unable to insert an additional BasicBlock between an indirectbr/callbr terminator and the successor blocks. This is needed by Polly to normalize the control flow before emitting its optimzed code. This patches rejects regions entered by an indirectbr/callbr to not fail later at code generation. This fixes llvm.org/PR51964 GitOrigin-RevId: 91f46bb77e6d56955c3b96e9e844ae6a251c41e9
