c17468d4ab MDEV-16191: Analyze format=json gives incorrect value for r_limit inside a dependent
subquery when ORDER BY is present

Currently for setting r_limit we divide with the number of iterations we invoke the dependent subquery.
This is not needed for the case of limit. For varying limits we produce the output that the limit varies with
execution.
Also there is a type for filtered , we forgot to multiply by 100 as it is represented as a percent.

2bc6e29afe MDEV-7943 - pthread_getspecific() takes 0.76% in OLTP RO
Pass THD to Sort_and_group_tracker::report_sorting().
This reduces number of pthread_getspecific() calls from 292 to 290.
