compiler: Add is_tagged_tuple instruction
Rewrite the instruction stream on tagged tuple tests. Tagged tuples means a tuple of any arity with an atom as its first element. Typically records, ok-tuples and error-tuples. from: ... {test,is_tuple,Fail,[Src]}. {test,test_arity,Fail,[Src,Sz]}. ... {get_tuple_element,Src,0,Dst}. ... {test,is_eq_exact,Fail,[Dst,Atom]}. ... to: ... {test,is_tagged_tuple,Fail,[Src,Sz,Atom]}. ...
