Hello everybody,

the attached patches clean up the i386 - Target a little bit.

* in i386.h better readable use of the prozessor TARGET defines
* in i386.md put the define_attr "cpu" at top and delete a
  double comment for it
* in i386.md combine identical define_insn with
  "&& TARGET_MOVE" and "&& !TARGET_MOVE"

Bye
	Frank
