* Changing size() return type from UInt32 to UInt64 to prevent overflow (this shouldn't break back compatibility).
* Removing "big cardinalities fix" for cardinalities >2^32/30 as it was very inaccurate and for estimates >2^32 it was trying to do 'log' of negative number which is NaN and it was casted to 0.
* Adding python script to show that intHash32 is not a good choice for HyperLogLog algorithm when it's used for linear counting branch of it.
* Adding bash script to test uniq, uniqHLL12, uniqCombined on different set cardinalities.
* Altering documentation of uniq* aggregate functions with recommendations to use uniq instead of uniqHLL12 or uniqCombined.
Interpreters/Compiler.cpp contained hard-coded paths for system's
includes needed for query compiler. These paths were not portable
between different Linux distros and gcc/clang versions. For example,
Debian/Ubuntu use /usr/lib/gcc/x86_64-linux-gnu/*/include,
RHEL/Fedora use /usr/lib/gcc/x86_64-redhat-linux/*/include,
others use /usr/lib/gcc/*/include (without x86_64-XXX triplet).
Patch 68850012b "Embedded compiler fixes" attempted to fix this problem
by adding CMAKE_LIBRARY_ARCHITECTURE after /usr/lib. Unfortunally,
CMAKE_LIBRARY_ARCHITECTURE is not defined on RHEL/Fedora because someone
decided to omit "-gnu" from x86_64-redhat-linux (see RHBZ#1531678).
Patch 70e35d0bc "Build fixes (#1718)" added a workaround for
undefined CMAKE_LIBRARY_ARCHITECTURE on RHEL/Fedora, but hasn't fixed
problem with missing /usr/lib/gcc/x86_64-redhat-linux/*/include/
in the list of hardcoded paths.
Remove hard-coded paths and get the list of `-isystem` includes directly
from bundled clickhouse-clang.
Other changes:
- Enable RPATH for the build directory to get working binaries
without installing them by `make install`.
