Summary: Targets like ARM, MSP430, PPC, and SystemZ have complex behavior when printing the address of a MachineOperand::MO_GlobalAddress. Move that handling into a new overriden method in each base class. A virtual method was added to the base class for handling the generic case. Refactors a few subclasses to support the target independent %a, %c, and %n. The patch also contains small cleanups for AVRAsmPrinter and SystemZAsmPrinter. It seems that NVPTXTargetLowering is possibly missing some logic to transform GlobalAddressSDNodes for TargetLowering::LowerAsmOperandForConstraint to handle with "i" extended inline assembly asm constraints.
