Remove obsolete comments about small and large object heaps.
It looks like somebody intended to perform segregation of objects by
their size. This was never implemented and the terminology is similar
to what is used by a forthcoming API.

-How will this be used?
-allocating/freeing: Heap.c just wants to say "alloc(n)" and get a ptr
- - if allocating in large doesn't work, try allocating from small
-Heap.c will use HeapSource.h; HeapSource.c will do the right thing
- between small and large
- - some operations should be abstracted; put in a structure
-
-How do we manage the size trade-offs?
-- keep mspace max footprint clamped to actual footprint
-- if small-alloc returns null, adjust large vs. small ratio
- - give small all available slack and retry
- - success or fail, snap back to actual footprint and give rest to large
-
-managed as "small actual" + "large actual" + "delta to allowed total footprint"
-- when allocating from one source or the other, give the delta to the
- active source, but snap back afterwards
-- that may not work so great for a gc heap, because small will always consume.
- - but we need to use the memory, and the current max is the amount we
- need to fill before a GC.
-
-Find a way to permanently steal pages from the middle of the heap
- - segment tricks?
-
-Allocate String and char[] in a separate heap?
-
-Maybe avoid growing small heap, even if there's slack? Look at
-live ratio of small heap after a gc; scale it based on that.
