I am not guru in GNU AS. I am not guru in GCC. This is my 
first patch.
May be later...

Not an immovable, but slow movable. Step by step. First 
step - create
GCC - AS interface for optimization options. Second step - 
sync cpu-type
options. Third - add optimizations to AS, that impossible 
to do on GCC level. Then add .tune directive. And so on...

Every big project, especially community-project, have to 
be very conservative. Many small step changes better then 
one global change.
Because big change results many bugs and a lot of headache 
for users
and developers. It's required very serious reason for 
global change.

Right, but one note - it's required some control for 
enable/disable optimization on some code fragments (for 
human-optimized assembler routines).
