  -----------
  [VectorCombine] Fix crash in scalarizeVPIntrinsic (#72039)

When getSplatOp returns nullptr, the intrinsic cannot be scalarized.
This patch includes a test case that fixes a crash from trying to
scalarize the VPIntrinsic when getSplatOp returns nullptr.

This fixes https://github.com/llvm/llvm-project/issues/72034.
