internal/fuzz: fix bugs with minimization This pulls in some code and tests from CL 353355. This change makes some refactors for when we read to and write from memory during minimization. That fixes a bug when minimizing interesting inputs. Now, if an error occurs while minimizing an interesting input, that value will continue to be minimized as a crash, and returned to the user. This change also allows minimization of a crash that occurred during the warmup phase. We don't want to minimize failures in the seed corpus, but if an entry in the cache causes a new failure, then there's no compelling reason why we shouldn't try to minimize it.
