Update calls_comdat_local in cgraph_node::create_version_clone

[Jan Hubicka]

Hi,
This patches fixes ICE when ipa-split is run from ipa-profile.  In normal
computation we recompute the flag elsewhere, but it is supposed to be kept
up-to-date by passes possibly modifying it.

Bootstrapped/regtested x86_64-linux, comitted.

gcc/ChangeLog:

        * cgraphclones.cc (cgraph_node::create_version_clone): Recompute
        calls_comdat_local
