Add annotations for likely/unlikely
In a correct Erlang programs, we can expect that:
* A GC test instruction (such as test_heap) is more likely
not to do the GC.
* A BIF is more likely to succeed than to fail.
* A BIF is more likely to fail in a guard than in a body.
* An apply or fun call is likely to succeed.
Annotate conditions accordingly.
