1dd3ea5515 Make OptimizeBlock take a MachineFunction::iterator instead of a 
MachineBasicBlock* as a parameter so that nxext() and prior() helper
functions can work naturally on it.

b28bc78d0a Use next() helper to make code more readable. Use 
MachineFunction::iterator instead of MachineBasicBlock* to avoid
dereferencing end iterators.

143aeb646c Use MachineFunction::iterator instead of a MachineBasicBlock* because 
FallThrough maybe == to MF.end().

9abd4de830 Convert a few assertions with side-effects into regular old runtime checks. 
These side-effects seem to make a difference when using llc -march=sparcv9
in Release mode (i.e., with -DNDEBUG); when they are left out, lots of
instructions just get dropped on the floor, because they never end up
in the schedule.
