ARM instructions that are both predicated and set the condition codes

have been printed with the "S" modifier after the predicate. With ARM's
unified syntax, they are supposed to go in the other order. We fixed this
for Thumb when we switched to unified syntax but missed changing it for
ARM. Apparently we don't generate these instructions often because no one
noticed until now. Thanks to Bill Wendling for the testcase!

All registers created during splitting or spilling are assigned to the same

When splitting or rematting, we may not spill at all. In that case the stack

Before we would also split around a loop if any peripheral block had multiple
