MachineBasicBlock* as a parameter so that nxext() and prior() helper
functions can work naturally on it.

MachineFunction::iterator instead of MachineBasicBlock* to avoid
dereferencing end iterators.

These side-effects seem to make a difference when using llc -march=sparcv9

Use LiveRange's iterator types and operations instead of ValueSet's.

SetVector<Value *> data member.
Add << operator for LiveRanges (a dumb one, for now.)
