[committed] testsuite: Fix local labels [PR122378]

[Paul-Antoine Arras]

r16-4540-g80af807e52e4f4 exposed a bug in two testcases where the 
declaration of local labels was wrongly commented out. That caused 
"duplicate label" errors.
Uncommenting declarations fixes it.

Committed as an obvious fix to my own patch.
