IMHO, the least intrusive way of using a debug counter in scheduler is 
to place into instruction choosing module and make scheduler to chose 
next instruction at all times.  I have successfully used this technique 
in debugging selective scheduler and believe it will suit haifa 
scheduler perfectly.

I've attached a patch that moves dbg_cnt to choose_ready () routine, but 
at this point have no time to test it for usability (though it compiles 
fine on x86_64).  If the patch won't work please let me know and I'll 
fix it during the weekend.
