This change makes it so that we check whether scavAddr is actually mapped before trying to look at the summary for the fast path, since we may segfault if that that part of the summary is not mapped in. Previously this wasn't a problem because we would conservatively map all memory for the summaries between the lowest mapped heap address and the highest one. This change also adds a test for this case.
