9bce44c8cc Entirely eliminate all patterns and expanders from this file. We shall go
with an incremental approach rather than a revolutionary approach.

d20c857ba0 Move the 'Expander' node to later in the file, with the other experimental
stuff.  The pattern becomes a list, add some stuff, add some comments.

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().

c21741420c I'm pretty sure that ba is branch always, which is a barrier. Brg should

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.
