[SVE] Add warnings checks in four more LLVM SVE tests

I have added CHECK lines to the following tests:

  llvm/test/CodeGen/AArch64/sve-breakdown-scalable-vectortype.ll
  llvm/test/CodeGen/AArch64/sve-calling-convention-tuple-types.ll
  llvm/test/CodeGen/AArch64/sve-intrinsics-create-tuple.ll
  llvm/test/CodeGen/AArch64/sve-intrinsics-loads.ll

since they are now free of warnings related to invalid use of
EVT::getVectorNumElements() and VectorType::getNumElements().
