Before this patch DAGCombine crashed wth the following error while
attempting to combine vst1x and base address update:

  unexpected intrinsic for Neon base update
  UNREACHABLE executed at llvm-project/llvm/lib/Target/ARM/ARMISelLowering.cpp:14089!

cause combining for vst1x is requested but has been never actually implemented.
