[Polly] Fix two testcases

[philip.pfaffe]

Summary

Trivial fix for two testcases. When Polly isn't linked into opt, idependent of whether it's built in-tree or not, these testcases forget to load the appropriate library.

Thank you Philipp! This is really useful.

Btw, as you seem to submit changes more than just occasionally, it might make sense to ask Christ for commit access. Patches like this one are a perfect example for patches that can be reviewed post-commit (no separate review thread is needed).
