Annotate some LOOP tests with ANSI-SPEC-PROBLEM
Fixes #14 (closed)
This marks tests
:ansi-spec-problem to take into account that the values of iteration
FINALLY are effectively undefined by the spec. This way,
testers can avoid running these test cases if they want to avoid testing
behaviour that is defined in contradictory manners.
Removal of these test cases should perhaps be considered in the future.
