sdl-ios-xcode: src/cpuinfo/SDL

annotate src/cpuinfo/SDL_cpuinfo.c @ 4386:dcb26ac38e6b SDL-1.2

Fixed crash - need to save and restore rbx around cpuid, since the compiler may be assuming the stack pointer isn't being modified when filling in %0. I did it around each call to cpuid which isn't strictly necessary, but is definitely future proof. :)
