>OP_MakeRecord creates a record from a given range of registers
>and stores that record in a specified register. But now even
>secondary indexes with non-default ON CONFLICT clause doesn't
>need it, it is necessary only for primary key indexes. However
>that unnecesary opcodes appear in INSERT listings. This patch
>contains a fix for that.
