--- Comment #13 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
For calls of interposable function, the result of ipa-pure-const are not used.
So this is why we are trying to skip it. ipa-pure-const will detect the
property, will call i.e. set_nothrow_flag which will do nothing since the
symbol is interposable.

I think we simply want to drop the flag_lto check.  LTO only makes a difference
for ipa-pure-const, but not for local one and this is gating local pure const. 
Looking at history, this is a result of commonising the lto/non-LTO path and
then separating it again.
