Changes in directory llvm/lib/CodeGen/SelectionDAG:

ScheduleDAGSimple.cpp updated: 1.21 - 1.22
---
Log message:

Added an automatic cast to std::ostream* etc. from OStream. We then can
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

Log message:

It seems the llvm::OStream class does not handle stream manipulators.
For now, just grab the stream and perform the output on it directly.
