0b47f4a9e9 Fix optimize_trivial_count_query with partition predicate 
Consider the following example:

    CREATE TABLE test(p DateTime, k int) ENGINE MergeTree PARTITION BY toDate(p) ORDER BY k;
    INSERT INTO test VALUES ('2020-09-01 00:01:02', 1), ('2020-09-01 20:01:03', 2), ('2020-09-02 00:01:03', 3);

- SELECT count() FROM test WHERE toDate(p) >= '2020-09-01' AND p <= '2020-09-01 00:00:00'
  In this case rpn will be (FUNCTION_IN_RANGE, FUNCTION_UNKNOWN (due to strict), FUNCTION_AND)
  and for optimize_trivial_count_query we cannot use index if there is at least one FUNCTION_UNKNOWN.
  since there is no post processing and return count() based on only the first predicate is wrong.

  Before this patch FUNCTION_UNKNOWN was allowed for optimize_trivial_count_query, and the result was wrong.

And two examples above just to show the difference, the behaviour hadn't been changed with this patch:

- SELECT * FROM test WHERE toDate(p) >= '2020-09-01' AND p <= '2020-09-01 00:00:00'
  In this case will be (FUNCTION_IN_RANGE, FUNCTION_IN_RANGE (due to non-strict), FUNCTION_AND)
  so it will prune everything out and nothing will be read.

- SELECT * FROM test WHERE toDate(p) >= '2020-09-01' AND toUnixTimestamp(p)%5==0
  In this case will be (FUNCTION_IN_RANGE, FUNCTION_UNKNOWN, FUNCTION_AND)
  and all, two, partitions will be scanned, but due to filtering later none of rows will be matched.
