runtime: remove useless heap_objects accounting

This change removes useless additional heap_objects accounting for large
objects. heap_objects is computed from scratch at ReadMemStats time
(which stops the world) by using nlargealloc and nlargefree, so mutating
heap_objects turns out to be pointless.

As a result, the "large" parameter on "mheap_.freeSpan" is no longer
necessary and so this change cleans that up too.
