I played around a little with this (the patch to get the scheduler to 
place dependent insns into the ready list as soon as their depedencies
were resolved) and couldn't ever get the trivial example to fire the
PA equivalent of sethi/lo_sum in the same cycle -- even after hacking up
my pa.md to have an issue/ready delay of zero for ALU insns.

Maybe I'm missing something...
