Suppressing code motion of constant values...

There was a code snippet and discussion of the idea of
suppressing hoisting constants outside of loops at
lower optimization levels.

I thought at the time that this wasn't a winner for me, but in
looking at some generated code for the SHARC DSP chip, it
appears that this is causing me to use more registers than
I need.

Can someone resend that code fragment?  It was a patch to loop.c
if I remember correctly.
