e7ad7b2f2a Replace patterns 0, 4, and 5 with simpler heirarchical definitions that use the 
official PowerPC instruction format lingo: X- and D-form.

MachineBasicBlock* as a parameter so that nxext() and prior() helper

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

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.
