Introduce uniqCombined64() to get sane results for cardinality > UINT_MAX
...
By default uniqCombined() uses 32-bit hash for all types except String,
so this means that you cannot use uniqCombined() with i.e UInt64 and
cardinality > UINT_MAX, although you can use uniqCombined(toString())
and this will lead to 64-bit hash, but will not have good performance.
So uniqCombined64() had been introduced to fix this.
