[ms-inline asm] Add support in the X86AsmPrinter for printing memory references in the Intel syntax. The MC layer supports emitting in the Intel syntax, but this would require the inline assembly MachineInstr to be lowered to an MCInst before emission. This is potential future work, but for now emitting directly from the MachineInstr suffices. llvm-svn: 165173

[ms-inline asm] Force the use of a base pointer if the MachineFunction includes MS-style inline assembly. This is a follow-on to r175334. Forcing a FP to be emitted doesn't ensure it will be used. Therefore, force the base pointer as well. We now treat MS inline assembly in the same way we treat functions with dynamic stack realignment and VLAs. This guarantees the BP will be used to reference parameters and locals. rdar://13218191 llvm-svn: 175576
