RegisterPressureTracker: unify virtual registers and physical regunits.
...
Now that live register units are tracked individually, the code can be simplified.

RegisterPresssureTracker: Track live physical register by unit.
...
This is much simpler to reason about, more efficient, and
fixes some corner cases involving implicit super-register defs.
Fixed rdar://12797931.

Sort the #include lines for the include/... tree with the script.

AKA: Recompile *ALL* the source code!
This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.
