[PATCH] x86: cmpxchg improvements This adjusts i386's cmpxchg patterns so that - for word and long cmpxchg-es the compiler can utilize all possible registers - cmpxchg8b gets disabled when the minimum specified hardware architectur doesn't support it (like was already happening for the byte, word, and long ones).
