Fix redirection in ipa.c

[Jan Hubicka]

Hi,
this patch fixes ICE when edge redirection happens just before summary 
generation.
At that time we still don't want edges to be redirected when underlying 
statements
are not.

Bootstrapped/regtested x86_64-linux, comitted.

        * ipa.c (walk_polymorphic_call_targets): Fix redirection before IPA
        summary generation.
