The utility allows to compare performance and memory requirements
for following hashtables: FixedConcurrentHashTable, ConcurrentHashTable,
Intel TBB concurrent_unordered_map, libcuckoo cuckoohash_map,
std::unordered_map, llvm::DenseMap.

To obtain Intel threading building block library visit https://github.com/oneapi-src/oneTBB.
Build library according to the instructions.
Add following into the llvm/tools/check-hashtable/CMakeLists.txt

include_directories( oneTBB/install/include )

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wl,oneTBB/install/lib/libtbb.so ")

To obtain libcuckoo library visit https://github.com/efficient/libcuckoo
Build library according to the instructions.
Add following into the llvm/tools/check-hashtable/CMakeLists.txt

include_directories( libcuckoo/install/include )

Depends On D125979 <https://reviews.llvm.org/D125979>, D132455 <https://reviews.llvm.org/D132455>
