Subject: Scheduler cleanups, 4/N

We have a mechanism to prevent the scheduler from touching certain
blocks; this is used by modulo scheduling. sched-ebb does not honor this
flag currently; this patch fixes it. Bootstrapped and tested on
i686-linux (pointlessly... but it's also used in our local tree for a
new target, TI C6X).
