    ipa/103989 - tame IPA optimizations at -Og

    With -Og we are not prepared to do cleanup after IPA optimizations
    and dead code exposed by those confuses late diagnostic passes.
    This is a first patch removing unwanted IPA optimizations, namely
    both late modref and pure-const analysis.
