Option setter for OS-allocated memory.
The option specifies a type for gathering internal statistics of large (OS-allocated) memory blocks that is too big to maintain by Michael's heap (with default sizeclass_selector, the block that large than 64K is not maintained by Michael's heap and passed directly to system allocator).
Note that OS-allocated memory statistics does not include memory allocation for heap's internal purposes. Only direct call of
alloc_aligned for large memory block is counted.
