--- Comment #49 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Patch posted for the inline heuristics change
https://gcc.gnu.org/pipermail/gcc-patches/2020-October/556685.html

Also opened spearate PR on builtin_constant_p folding. I am not sure how to
implement that correctly (what are the conditions that make this valid -
perhaps for all "i op cst" after all?)

Martin, how does the if chain conversion behave on the example?
