Match: Add form 2 for unsigned SAT_MUL

This patch would like to try to match the the unsigned
SAT_MUL form 2, aka below:

  #define DEF_SAT_U_MUL_FMT_2(T)               \
  T __attribute__((noinline))                  \
  sat_u_mul_##T##_fmt_2 (T a, T b)             \
  {                                            \
    T result;                                  \
    if (__builtin_mul_overflow(a, b, &result)) \
      return -1;                               \
    else                                       \
      return result;                           \
  }

While T is uint8_t, uint16_t, uint32_t and uint64_t.
