beam_makeops: Eliminate crash because of unsafe packing
Consider an hypothetical instruction:
do_something x x c
The loader would crash if we tried to load an instance of the
instruction with the last operand referencing a literal:
{do_something,{x,0},{x,1},{literal,{a,b,c}}}
Teach beam_makeops to turn off packing for such unsafe instructions.
