d435532c68 Adapt range search algorithm to high cardinality case 
+ range search done in steps of some number of rows.
  Controled by new
  setting `distinct_in_order_range_search_step`. By default 0, i.e.
  whole chunk
+ before start binary search, linear probing is done on each step (32
  rows currently)

ee0f2651ee Revert "Fix converting types for UNION queries (may produce LOGICAL_ERROR)" 
This fix is incorrect, and it introduce new issues, in particular it
may breaks UNION queries w/o column aliases, i.e.:

    SELECT a, b, c FROM (SELECT 3 AS a, 2147483647 AS b, 1048575 AS c UNION ALL SELECT -2, NULL, -2) AS js1 ORDER BY a

Fix various clang-tidy warnings 
When I tried to add cool new clang-tidy 14 warnings, I noticed that the
current clang-tidy settings already produce a ton of warnings. This
commit addresses many of these. Almost all of them were non-critical,
i.e. C vs. C++ style casts.
