 MachRegs.h requires ghcautoconf.h to be included before it, because, in
 the case of ARM processors, it needs to know what ARM variant is being
 used.

 This patch fixes that in includes/CodeGen.Platform.hs, otherwise there is
 a mismatch between the compiler and llvm.

 Perhaps it needs to be made more robust by instead including ghcautoconf.h
 from MachRegs.h? Otherwise someone else could easily break it. I
 originally didn't do this, because it wasn't done anywhere else.

 Suggested fix attached.
