G1: deal with fragmentation while copying objects during GC

        Currently, when an allocation request fails on a region we retire that region and grab a new one. This works fine most of the time when allocation requests are small. However, if the GC comes across some large-ish objects every now and then, that does not fit in the remainder of the current GC alloc region, we'll retire that region, maybe wasting a fair amount of space in it. It'd be good if we minimized how much space we waste because of this fragmentation.
