Is this comment accurate and up to date?  I think it covers JSFunction, JSObject
and the new proxy types now, right?

No, a proper version is on HEAD already (from a different branch). I rebased to
make this change disappear.

 macro IS_SPEC_OBJECT(arg) = (%_IsSpecObject(arg));
+macro IS_SPEC_FUNCTION(arg) = (%_ClassOf(arg) == 'Function');
 
 # Inline macros. Use %IS_VAR to make sure arg is evaluated only once.
 macro NUMBER_IS_NAN(arg) = (!%_IsSmi(%IS_VAR(arg)) && !(arg == arg));
