    Fix stmt_kills_ref_p WRT external throws

    Add missing check to stmt_kills_ref_p for case that function
    is terminated by EH before call return value kills the ref. In the PR
    I tried to construct testcase but I don't know how to do that until I
    annotate EH code with fnspec attributes which I will do in separate patch
    and add a testcase.
