    Use UINT128_T support flag from configure
    
    Current check for __uint128_t in hash.c is not valid, since it ignores
    compilers other than gcc. We hit this on lcc on e2k platform.
    
    Configure script properly checks from 128-bit data types support and
    sets HAVE_UINT128_T accordingly. This approach is already used within
    ruby at bignum.c, random.c, etc.
    
    Probably hash.c is an overlooked remnant of old days. This patch fixes
    this.

    hash.c: use uint128_t
    
    * hash.c (mult_and_mix): use uint128_t instead of __uint128_t.
