    ipa: Don't disable function parameter analysis for fat LTO

    Update analyze_parms not to disable function parameter analysis for
    -ffat-lto-objects.  Tested on x86-64, there are no differences in zstd
    with "-O2 -flto=3Dauto" -g "vs -O2 -flto=3Dauto -g -ffat-lto-objects".

            PR ipa/116410
            * ipa-modref.cc (analyze_parms): Always analyze function parame=
ter
            for LTO.
