With -fprofile-use we get
Evaluating opportunities for MorphologyApply/3266.

So no cloning of MorphologyApply
For GetVirtualPixelsFromNexus
Evaluating opportunities for GetVirtualPixelsFromNexus/487.

....
- considering value 1 for param #5 const size_t (caller_count: 12)
good_cloning_opportunity_p (time: 1, size: 537, count_sum: 19110748
(adjusted), overall time saved: 19110748 (adjusted), scc) -> evaluation:
21352.79, threshold: 500
not cloning: time saved is not hot

(adjusted), overall time saved: 38221496 (adjusted), scc) -> evaluation:
35390.27, threshold: 500
Creating a specialized node of GetVirtualPixelsFromNexus/487.
replacing param #5 const size_t with const 1
So at least here the cloning now works.
