Functions
static LaneBitmask	getDefRegMask (const MachineOperand &MO, const MachineRegisterInfo &MRI)
static void	collectVirtualRegUses (SmallVectorImpl< VRegMaskOrUnit > &VRegMaskOrUnits, const MachineInstr &MI, const LiveIntervals &LIS, const MachineRegisterInfo &MRI)
static LaneBitmask	getLanesWithProperty (const LiveIntervals &LIS, const MachineRegisterInfo &MRI, bool TrackLaneMasks, Register Reg, SlotIndex Pos, function_ref< bool(const LiveRange &LR, SlotIndex Pos)> Property)

static LaneBitmask	findUseBetween (unsigned Reg, LaneBitmask LastUseMask, SlotIndex PriorUseIdx, SlotIndex NextUseIdx, const MachineRegisterInfo &MRI, const SIRegisterInfo TRI, const LiveIntervals LIS, bool Upward=false)
	Mostly copy/paste from CodeGen/RegisterPressure.cpp Helper to find a vreg use between two indices {PriorUseIdx, NextUseIdx}.
