23f676e21d Revert "Give internal classes hidden visibility." 
It works with clang, but GCC has different rules so we can't make all of those
hidden. This reverts commit r190534.

a98c778194 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. =]

491e6e24f7 Use std::vector instead of a hard-coded array. The length of that array could 
get *very* large, but we only need it to be the size of the number of pregs.

46b89e05fd 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.

8954ccb109 Remove some old experimental code that is no longer needed. Remove additional, speculative scheduling pass as its cost did not translate into significant performance improvement. Minor tweaks.

0b5b62bfcf Allow the aggressive anti-dep breaker to process the same region multiple times. This is necessary because new anti-dependencies are exposed when "current" ones are broken.
