Relates: #4649 This commit fixes a bug in the IsLong implementation, and prefers reading long values over double values in PrimitiveObjectFormatter when the bytes represent a valid long value, to avoid floating point rounding errors that may happen when parsing a double from a long value. The bug in IsLong was that the loop over the array segment bytes was exiting early when the count of bytes was the same as long.Min/MaxValue length, and the current loop byte is less than the byte at index in long.Min/MaxValue. In this scenario, it should not exit early, but not continue to check following loop bytes against byte at index in long.Min/MaxValue. Following loop iterations still need to check whether remaining bytes are numbers.
