Hi,

In early_inliner we do recompute inline summaries for edges after optimize_inline_calls, but check this summary exists in case new edges appear.  But then it calls inline_update_overall_summary which also going through edges inline summaries but with no check this time causing segfault.  This patch fixes it.  Bootstrapped and regtested for x86_64-unknown-linux-gnu.  Is it OK for trunk and gcc-5-branch?

Thanks,
Ilya
