    testsuite: prune -freport-bug output
    
    When the compiler defaults to -freport-bug, a few dg-ice tests fail
    with:
    
    Excess errors:
    Preprocessed source stored into /tmp/cc6hldZ0.out file, please attach this to your bugreport.
    
    We could add -fno-report-bug to those tests.  But it seems to me that a
    better fix would be to prune the "Preprocessed source stored..." message
    in prune_gcc_output.
    
    gcc/testsuite/ChangeLog:
    
            * lib/prune.exp (prune_gcc_output): Also prune -freport-bug output.
