No details to give at the moment.  Just a strong feeling that this stuff will
be changing in the not too distant future.

Actually, if we had to do it all over again, I'd leave a little more room
between the -O options so that we could have a little more fine grained
control over optimizations.  The jump from -O0 to -O1 is pretty big.  I'm
often asked about the possibility of having something in-between -- like
just run a simple jump optimizer and delete nop copies, but not auto
register allocation, combine, cse, etc etc etc.
