Tomasz Grabiec 320f6bf220 Merge 'test: perf: perf_simple_query: collect allocation and task statistics' from Avi Kivity

Calculate and display the number of memory allocations and tasks
executed per operation. Sample results (--smp 1):

180022.46 tps (90 allocs/op, 20 tasks/op)
178963.44 tps (90 allocs/op, 20 tasks/op)
178702.41 tps (90 allocs/op, 20 tasks/op)
177679.74 tps (90 allocs/op, 20 tasks/op)
179539.36 tps (90 allocs/op, 20 tasks/op)

median 178963.44 tps (90 allocs/op, 20 tasks/op)
median absolute deviation: 575.92
maximum: 180022.46
minimum: 177679.74

This allows less noisy tracking of how some changes impact performance.

Closes #8425
