2d2e738085 Add CRC32IEEE()/CRC64() support 
zlib's implementation uses CRC-32-IEEE 802.3 polynomial (0xedb88320) but
with starting value 0xffffffff, so introduce another crc32
implementation - CRC32IEEE that has starting value - 0

Also add CRC64 with ECMA polynomial.

v2: s/crc*_data./crc*_data./ to avoid conflicts with other crc32.h in contrib
v3: join with existing CRC32()

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.

Requires: #7213

420089c301
Add new dictionary layout (sparse_hashed) that is more memory efficient 
With this new layout, sparsehash will be used over default HashMap,
sparsehash is more memory efficient but it is also slower.

So in a nutshell:
- HashMap uses ~2x more memory then sparse_hash_map
- HashMap ~2-2.5x faster then sparse_hash_map
(tested on lots of input, and the most close to production was
dictionary with 600KK hashes and UInt16 as value)

TODO:
- fix allocated memory calculation
- getBufferSizeInBytes/getBufferSizeInCells interface
- benchmarks

v0: replace HashMap with google::sparse_hash_map
v2: use google::sparse_hash_map only when <sparse> isset to true
v3: replace attributes with different layout
v4: use ch hash over std::hash
