Subject: [PATCH 1/1] sql: IS is only applicable when dealing with NULL
According to ANSI Standard IS/IS NOT can be used to determine
if values is null. At the same time in SQLite3 IS/IS NOT have an
additional function - it can be used to check equality of two
values. This patch removes that additional function.
Closes #2136
