During minimization, the "canonical inputs" (vals) are updated as viable minimized values are found. Previously, these bytes could be changed later during minimization. This patch updates the minimization code to revert the bytes back when a candidate doesn't pass the minimization checks. Another approach was in CL 340630 which would make a new allocation each time a candidate was attempted. This will get very expensive very quickly, as minimization can run several thousand times for every new crash and every newly discovered interesting input. Credit to Steven Johnstone (steven.james.johnstone@gmail.com) for the "single_bytes" test which was added to minimize_test.go.
