Re: sched2, ret, use, and VLIW bundling

[DJ Delorie]

Some progress... the scheduler is willing to schedule them together if
I define the SCHED_REORDER2 hook (just SCHED_REORDER was
insufficient), and always return the number of ready insns.  In my
case, the VLIW packing restrictions are fully defined by a DFA; I
don't need to further restrict packing.
