Make reallocation of large objects reliable.
If ThreadHeap::reallocate<T>() is called with a size that's
equal or greater to the large object threshold (64k, currently),
make sure it ends up being allocated as a large object.
Large objects would previously be attempted allocated on a normal arena,
hoping that the allocation couldn't be serviced by bump allocation, but
fall into an out-of-line allocation.
