  Changed paths:
    M llvm/include/llvm/CodeGen/MachineScheduler.h
    M llvm/lib/CodeGen/MachineScheduler.cpp

  Log Message:
  -----------
  Add a policy to enable computing SchedDFSResult.

Summary:
Make GenericScheduler compute SchedDFSResult on initialization if
the policy is set. This makes it possible to create classes
that extend GenericScheduler and rely on the results of SchedDFSResult,
e.g. to perform subtree scheduling.

NFC unless the policy is set.
