PR middle-end/30696 (OpenMP and undefined symbols)

[Jan Hubicka]

Hi,
the problem is that early inliner is bit too active on removing offline copy of
function foo that is also accessed by unanalyzed yet openmp function.

bootstrapped/regtested the patch on i686-linux and comitted.  I will
commit the testcase shortly too - in the first round of testing I
misplaced it and it didn't pass but I wanted thonight c++ tester to take
the patch.
inline void foo() {}

int main()
{
    foo();

#pragma omp parallel for
    for ( int i=0; i<1; ++i )
        foo();

    return 0;
}

	* ipa-inline.c (cgraph_clone_inlined_nodes): When there are unanalyzed
	nodes in cgraph, don't remove offline copy of the function.
