bricks: rework tests

On some architectures this test fails due to several
reasons:
    - missing headers
    - use of valueAt instead of count in ConCS. Indeed,
    valueAt acts similarly to count but avoids some validity
    check that are required when the hashmap is growing.

This patch also:
     - removes inaccurate comments from bricks.test.
     - test more features for hashset.
