[Polly] Add check-polly-tests build target.

[Meinersbur]

Summary

The check-polly-tests target runs regression/unit tests but without checking format. This is useful to not having to reload a file in an open editor (which eg. clears the undo buffer, moves cursor/window position) when running polly-update-format.

After this change, the following test targets exist:

• check-polly-unittests to run unittests only
• check-polly-tests to run unit and regression tests
• polly-check-format to check formatting using clang-format
• check-polly to run them all

As a side-effect, when running check-polly, polly-check-format and run in parallel (instead of polly-check-format first).
