Some benchmark queries fail or produce incorrect results

[andygrove]

Describe the bug

The following queries produce the correct results (SF=1).

• q4
• q12
• q13
• q14

The following queries produce the correct results (SF=1) except for rounding differences due to bugs in the benchmark (not casting utf8 to decimal correctly).

• q1
• q5
• q7
• q8
• q9
• q18
• q19

The following queries either fail to run or they produce the wrong results (SF=1).

• q2 wrong row count 100 vs 460
• q3 wrong row count 10 vs 11620
• q6 returns the wrong value
• q10 returns wrong number of rows 20 vs 37967
• q11 returns wrong number of rows 1048 vs 29571
• q15 returns wrong number of rows 1 vs 0
• Benchmark q16 fails #373
• q17 produces result with one row but value is null or empty
• q20 produces results that are almost correct but has an extra whitespace
• q21 returns the wrong number of rows 100 vs 411

q16 looks like it's a datafusion-proto issue: apache/datafusion#3820
