When lowering llvm::stackprotect intrinsic, the SDAG implementation checks useLoadStackGuardNode() to either create a LOAD_STACK_GUARD or use the first argument of the intrinsic. This check is not present in the IRTranslator, which results in always generating a LOAD_STACK_GUARD even if the target does not support it.
