Mop-up for AIX-ectomy: remove now-dead test code.

tglsfdc · tglsfdc · commit f0827b443e60 · 2024-02-28T14:34:19.000-05:00
Commit 0b16bb8 removed the test query added by commit 79b716c, but not the C-language support function used by that query. I don't see any plausible reason why we'd need that function again, so throw it overboard too.
