Description:
Rewrite CreateIteratorFromAccessPath() so that it is non-recursive, and thus needs a bounded amount of stack no matter the system.

How to repeat:
N/A

Suggested fix:
N/A

Documented fix as follows in the MySQL 8.0.29 changelog:

    Rewrote the internal CreateIteratorFromAccessPath() function so
    that it is no longer recursive; this is expected to reduce stack
    usage significantly when executing queries.

Closed.
