This replaces all uses of the mheap_.arena_* fields outside of mallocinit and sysAlloc. These fields fundamentally assume a contiguous heap between two bounds, so eliminating these is necessary for a sparse heap. Many of these are replaced with checks for non-nil spans at the test address (which in turn checks for a non-nil entry in the heap arena array). Some of them are just for debugging and somewhat meaningless with a sparse heap, so those we just delete. Updates #10460.
