Simplify beam_utils
When beam_utils was first written, it did not have the functions for testing whether a register was not used. Those were added later, in sort of a hacky way. Also, is_killed*() and is_not_used*() for Y registers would return the same answer. Fix that to make the API more consistent (an Y register can only be killed by a deallocate/1 instruction). We will need to change beam_trim to call beam_utils:is_not_used/3 instead of beam_utils:is_killed/3.
