This changes the encoding of values stored in exception objects from a typed uint16 array (a JSObject) to a {FixedArray} instead. Note that it increases the memory footprint of the encoding, but will allow accessing elements directly from generated code and also encode reference types properly. The memory footprint can/should be optimized only after the implementation is feature complete.

Originally timestamps were added in crrev.com/c/1159361 to ease debugging. Since then, however, timestamps were introduce to the LogDog viewer and are rendered in a separate column, making it easier to scan text for important messages starting with '>>>'. We do keep the log level, but make sure that it always takes a fixed width such that the actual messages are aligned vertically.
