  Log Message:
  -----------
  [NFCI][LoopUnrollAndJam] Changing LoopUnrollAndJamPass to a function
pass.

Summary: This patch changes LoopUnrollAndJamPass to a function pass, and
keeps the loops traversal order same as defined in
FunctionToLoopPassAdaptor LoopPassManager.h.

The next patch will change the loop traversal to outer to inner order,
so more loops can be transform.
