fix various armv8 and armv8 panics that should be Err.
in fact the decoder should _never_ panic. included here are tests that cover the entire 32-bit instruction space and ensure that decoding and display do not panic. these tests run uncomfortably slowly (1168s to decode the 4b "instruction" sequences on my desktop), but verify that panics are no longer an issue.
