84fbac5809 Move ScheduleDAGSDNodes.h to be a private header. Front-ends 
that previously included this header should include
SchedulerRegistry.h instead.

4350eb86a7 Add TargetInstrInfo::isSafeToMoveRegisterClassDefs. It returns true if it's safe to move an instruction which defines a value in the register class. Replace pre-splitting specific IgnoreRegisterClassBarriers with this new hook.

7a2e7e5c20 Revert the previous commit. It seems it didn't 
really solve the problem.  Also it changed the
name from libLLVMgold to LLVMgold (correcting
the name resulted in the original problem
suddenly reappearing).
