Code cleanup to remove confusing assertion
The code of add_ref/6 contained an assertion that somehow appeared twice. Also, a recent commit (2b2de61) suppressed an unmatched return warning in a non-optimal way. By changing the return type of hipe_bifs:add_ref/2 to be 'ok' instead of [] the code can be cleaned up and simplified. While at it, fixed the wrong indentation of some nearby code.
