Do not use more then 98K of memory for uniqCombined*

e373862c83 Do not use more then 98K of memory for uniqCombined* 
uniqCombined() uses hashtable for medium cardinality, and since
HashTable resize by the power of 2 (well actually HashTableGrower grows
double by the power of 2, hence HashTableGrower::increaseSize() should
be overwritten to change this), with 1<<13 (default for uniqCombined)
and UInt64 HashValueType, the HashTable will takes:

  getBufferSizeInBytes() == 131072

While it should be not greater then sizeof(HLL) ~= 98K, so reduce the
maximum cardinality for hashtable to 1<<12 with UInt64 HashValueType and
to 1<13 with UInt32, overwrite HashTableGrower::increaseSize() and cover
this using max_memory_usage.

f46c5a47c0 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.
