Hook up llc's -filetype=obj to use MCStreamer if an MCCodeEmitter is available.

Remove most of old Mach-O Writer support, it has been replaced by MCMachOStreamer

Further refactoring to completely remove MachOWriter and drive the object file
writer with the AsmPrinter MCInst/MCSection logic is forthcoming.
