Matthias Braun 2aa5727755 TargetRegisterInfo: Provide a way to check assigned registers in getRegAllocationHints()
Pass a const reference to LiveRegMatrix to getRegAllocationHints()
because some targets can prodive better hints if they can test whether a
physreg has been used for register allocation yet.
