fixes this.
The gcc-patches post said:
"This is bug. The cleanup is supposed to happen just before inlining functions
called once. The patch also adds the cleanup to same place into
do_whole_program_analysis and updates cgraphclones.c so we do not ice when
removing offline copy of the function after inlining."
but clearly that is too early, as the testcase shows.
