Hi John and Hans,

I don't know if I found right reviewers for this patch, but could you please have a look at it?
I found this problem while I was trying to profile a binary that is compiled with -pg and -O2 as I reported in bugzilla.

I know the better approach is to do function inlining first, then insert mcount calls for each function remained. But this can fix the problem in a simpler way as of now. If anyone can give me some guide or someone can move mcount insertion phase later, that would be also good.

Thanks,
Honggyu
