Represent RegUnit liveness with LiveRange instance
Previously LiveInterval has been used, but having a spill weight and
register number is unnecessary for a register unit.

Added -misched-regpressure option.
Register pressure tracking is half the complexity of the
scheduler. It's useful to be able to turn it off for compile time and
performance comparisons.

mi-sched: improve the generic register pressure comparison.
Only compare pressure within the same set. When multiple sets are
affected, we prioritize the most constrained set.

mi-sched: Precompute a PressureDiff for each instruction, adjust for liveness later.
Created SUPressureDiffs array to hold the per node PDiff computed during DAG building.
Added a getUpwardPressureDelta API that will soon replace the old
one. Compute PressureDelta here from the precomputed PressureDiffs.
Updating for liveness will come next.

MI Sched: Track live-thru registers.
When registers must be live throughout the scheduling region, increase
the limit for the register class. Once we exceed the original limit,
they will be spilled, and there's no point further reducing pressure.
This isn't a perfect heuristics but avoids a situation where the
scheduler could become trapped by trying to achieve the impossible.

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.
