gcc6-pr66688.patch
I think this just went latent with those changes. The problem I see is that
cleanup_control_flow_bb can be called before fixup_noreturn_call is performed,
and in that case can either find a noreturn call at the end of bb if -g0 or
can't if the noreturn call is followed by some debug stmts. This hunk fixes
the case so that it is handled the same.
