1. Fix incorrect fusion of div and rem …

   The JIT would generate code that calculated the remainder incorrectly
   for the following example:
   
       bug(Bin) ->
           N = byte_size(Bin),
           {N rem 128, N div 128}.
   
   Essentially, the JIT would rewrite the code like this:
   
       bug(Bin) ->
           N = byte_size(Bin),
           Q = N bsr 7,
           {Q band 16#7f, Q}.
   
   That is, the remainder would be calculated as `(N div 128) rem 128`.
   
   Fixes erlang#7566
