    Merge commit 598f21e9fcf7 from llvm git (by zhijian lin):

      [PowerPC] need to set CallFrameSize for the pass  PPCReduceCRLogicals
when insert a new block (#151017)

      In the [ [CodeGen] Store call frame size in
      MachineBasicBlock](https://reviews.llvm.org/D156113), it mentions When a
      basic block has been split in the middle of a call sequence. the call
      frame size may not be zero, it need to set the setCallFrameSize for the
      new MachineBasicBlock. but in the function `splitMBB(BlockSplitInfo
      &BSI)` in the llvm/lib/Target/PowerPC/PPCReduceCRLogicals.cpp , it do
      not setCallFrameSzie for the new MachineBasicBlock `NewMBB`, we will
      setCallFrameSzie in the patch.

      the patch fix the crash mention in
      https://github.com/llvm/llvm-project/pull/144594#issuecomment-2993736654

    This fixes "error in backend: Found 1 machine code errors" while
    crypto/openssh/packet.c for PowerPC64.
