[Bug optimization/13875] New: [tree-ssa] function not optimized

cc1plus -v
GNU C++ version 3.5-tree-ssa 20040123 (merged 20040102) (i686-pc-linux-gnu)
        compiled by GNU C version 3.5-tree-ssa 20040123 (merged 20040102).

generate-3.4.ii is the famous code from PR8361

cc1plus -quiet -fpreprocessed -O2 generate-3.4.ii -fdump-tree-optimized

Looking at the function HeuristicCounters::~HeuristicCounters() in
generate-3.4.ii.t35.optimized, it seems that this function has not been 
optimized, there are obvious jump threading opportunities.

It is strange that if -fno-inline is added to the command line, then 
HeuristicCounters::~HeuristicCounters() is optimized!
