This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Add the infrastructure for unittests to Polly and two simple tests for conversion between isl_val and APInt. In addition, a build target check-polly-unittests is added to run only the unittests but not the regression tests. Clang's unittest mechanism served as as a blueprint which then was adapted to Polly.
