We need to distinguish pointers to free spans, which indicate bugs in our pointer analysis, from pointers to never-in-the-heap spans, which can legitimately arise from sysAlloc/mmap/etc. This normally isn't a problem because the heap is contiguous, but in some situations (32 bit, particularly) the heap must grow around an already allocated region. The bad pointer test is disabled so this fix doesn't actually do anything, but it removes one barrier from reenabling it. Fixes #9872.
