Sort includes for all of the .h files under the 'lib' tree. These were
...
missed in the first pass because the script didn't yet handle include
guards.
Note that the script is now able to handle all of these headers without
manual edits. =]

get *very* large, but we only need it to be the size of the number of pregs.

Make post-ra scheduling, anti-dep breaking, and register scavenger (conservatively) aware of predicated instructions. This enables ARM to move if-conversion before post-ra scheduler.
