Fix evaluation of local functions for new-inference

Plus, additionally fix evaluation of generic local functions everywhere

 The problem was that in new-inference we create more substituted
 descriptors while old inference tries to preserve original ones.
 Later, backend fails to retrieve those descriptors as it uses originals.
 But, again, this worked only for simple functions, for generic functions
 debugger with new and old inference worked incorrectly
