Use std::vector instead of TargetRegisterInfo::FirstVirtualRegister. This time
make sure to allocate enough space in the std::vector.

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 thenumber 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.

and End arguments by-value rather than by-reference.

Anti-dependency breaking needs to be careful regarding instructions with
multiple register definitions.

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.

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.
