I think that for_each_rtx construct just sometimes tend you to change a way
algorithm works somewhat and still compilers are far away from being able
to repair such an problem.
BTW making for_each_rtx inline is just another papering around - gcc should
be able to do inlining around compilation units once...

OK. Lets try - I will send then the patch containing same code in for_each_rtx
and we can decide to make it inline eventually. Still there isn't equivalent
for the _PUSH macro, so many function will still have to recurse explicitly.
