testsuite: Add testcases for already fixed PR [PR100541]
These testcases started failing with r12-630 and one of them
got fixed with r12-4531 (aka PR102764 fix and r12-4616 further
improved the fix) and the other went latent in r12-2591 (i.e. threader
changes) and I believe was fixed for real by the PR102764 fix too.
