		Introduced hxcpp_api_level 310

		Returns stats on memory usage:
		- `MEM_INFO_USAGE` - estimate of how much is needed by program (at last collect)
		- `MEM_INFO_RESERVED` - memory allocated for possible use
		- `MEM_INFO_CURRENT` - memory in use, includes uncollected garbage.
			This will generally saw-tooth between USAGE and RESERVED
		- `MEM_INFO_LARGE` - Size of separate pool used for large allocs.  Included in all the above.
