virtual MCRegister	tryFindEvictionCandidate (const LiveInterval &VirtReg, const AllocationOrder &Order, uint8_t CostPerUseLimit, const SmallVirtRegSet &FixedRegisters) const =0
	Find a physical register that can be freed by evicting the FixedRegisters, or return NoRegister.

virtual bool	canEvictHintInterference (const LiveInterval &VirtReg, MCRegister PhysReg, const SmallVirtRegSet &FixedRegisters) const =0
	Find out if we can evict the live ranges occupying the given PhysReg, which is a hint (preferred register) for VirtReg.

bool	isUnusedCalleeSavedReg (MCRegister PhysReg) const
	Returns true if the given `PhysReg` is a callee saved register and has not been used for allocation yet.
