## Summary Add the memory boundary realloc test. When CONFIG_MM_SMALL enable and CONFIG_DEBUG_MM disable, **SIZEOF_MM_ALLOCNODE = 4, MM_MIN_CHUNK = 16, SIZEOF_MM_FRENODE = 12**.  In above figure, **HEAP_SIZE** is not aligned with **MM_MIN_CHUNK** (because **(2 * SIZEOF_MM_ALLOCNODE) != MM_MIN_CHUNK)**), nodeA is a malloced memory node, nodeB is a free memory node and adjacent to heap end node. In this situation, realloc the nodeA may lead the remain size be **(MM_MIN_CHUNK - 2 * SIZEOF_MM_ALLOCNODE) = 8**, which is not large enough to hold a free node, so software will assert fail at mm_heap/mm_realloc.c line: 319.
