2790ee3a8e Track IR ordering of SelectionDAG nodes 2/4. 
Change SelectionDAG::getXXXNode() interfaces as well as call sites of
these functions to pass in SDLoc instead of DebugLoc.

237980d752 Remove the MachineMove class. 
It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.

I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

245de3a31f Change getFrameMoves to return a const reference. 
To add a frame now there is a dedicated addFrameMove which also takes
care of constructing the move itself.

	instruction Rp = COMBINE_Ir_V4(0, Rx) to the uses of Rp:subreg_loreg.

c909ae62a5 Hexagon: Honor __builtin_expect by using branch probabilities. 
* lib/Target/Hexagon/HexagonInstrInfo.cpp (GetDotNewPredOp):
  Given a jump opcode return the right pred.new jump opcode with
  a taken vs not-taken hint based on branch probabilities provided
  by the target independent module.
  * lib/Target/Hexagon/HexagonVLIWPacketizer.cpp: Use the above function.
  * lib/Target/Hexagon/HexagonNewValueJump.cpp(getNewvalueJumpOpcode):
  Enhance existing function use branch probabilities like
  HexagonInstrInfo::GetDotNewPredOp but for New Value (GPR) Jumps.
