Match: Add form 3 for unsigned SAT_MUL

This patch would like to try to match the the unsigned
SAT_MUL form 3, aka below:

  #define DEF_SAT_U_MUL_FMT_3(NT, WT)             \
  NT __attribute__((noinline))                    \
  sat_u_mul_##NT##_from_##WT##_fmt_3 (NT a, NT b) \
  {                                               \
    WT x = (WT)a * (WT)b;                         \
    if ((x >> sizeof(a) * 8) == 0)                \
      return (NT)x;                               \
    else                                          \
      return (NT)-1;                              \
  }

While WT is  T is uint16_t, uint32_t, uint64_t and uint128_t,
and NT is is uint8_t, uint16_t, uint32_t and uint64_t.

gcc/ChangeLog:
