* config/i386/i386-c.c (ix86_target_macros_internal): Depending on

selected code model, define __code_mode_small__, __code_model_medium__,

__code_model_large__, __code_model_32__ or __code_model_kernel__.

* config/i386/cpuid.h (__cpuid, __cpuid_count) [__i386__]: Prefix

xchg temporary register with %k.  Declare temporary register as

early clobbered.

[__x86_64__]: For medium and large code models, preserve %rbx register.
