Innit.

  Trans_NS___cxx11_basic_string();

};

bool can_swizzle_scalar, backend_0;

void emit_instruction(int count) {
  bool splat = backend_0;
  bool swizzle_splat = can_swizzle_scalar;

  for (; count; count++)
    if (emit_instruction_elems[count])
      splat = swizzle_splat = false;

  Trans_NS___cxx11_basic_string constructor_op;
  if (splat)
    if (swizzle_splat)
