The grammar already marks these E_FTYPE_OBJECT and turns class lookup off
for them, but the code generator published every method the same way, so
a subclass's "object function sub" shadowed an inherited "function sub"
for ordinary instance calls. class.c now skips E_FTYPE_OBJECT in both
places it emits methods - memberFunctions[] and the
A4GL_add_datatype_function_i registrations - which leaves object
functions distinct from plain ones rather than a synonym for them.
