[ignition/turbofan] Wrap bytecode liveness bitvectors

Hi Ross,

Here's the bytecode liveness wrapper we discussed in the bytecode analysis CL,
that I punted on. I'm not sure this is worth the extra code, WDYT?

I actually like these changes, I think it makes the code which checks and uses
the liveness information much clearer. Jaro, what do you think, worth the extra
code?

[Jarin, 2016-12-08 12:05:24]

lgtm. I like it!
