In order to simplify the dynamic VTCM memory pool, it will support the following alignments:
2k boundaries, allocated from the front of the pool in the smallest open spot possible.
128 byte boundaries, allocated from the end of the pool.
Made this support explicit, modified test to hit these boundaries.
