hash table. This also removes ValueT parametrization for the hash table data
structure. Please refer to JIRA tickets QUICKSTEP-28 and QUICKSTEP-29 for more
details.
TPC-H query 01 sees significant performance improvements with these changes.
Currently, only SeparateChaining hash table type is supported.
