[PATCH] Fix PR60327 - dealII and Xalanbmk ICEing with LTO

[Richard Biener]

This fixes the ICE on our regular -flto-partition=none testers
which sees an edge w/o call-stmt after inlining (see the PR
for details).  I'm not sure this is supposed to happen but the
following re-instantiates the guard to inline_update_overall_summary
which was present before the last change to that area.

LTO bootstrap / regtest running on x86_64-unknown-linux-gnu, ok?

Thanks,
Richard.
