arch/tile: use better definitions of xchg() and cmpxchg()
These definitions use a ({}) construct to avoid some cases where
we were getting warnings about unused return values. We also
promote the definition to the common <asm/atomic.h>, since it applies
to both the 32- and 64-bit atomics.
In addition, define __HAVE_ARCH_CMPXCHG for TILE-Gx since it has
efficient direct atomic instructions.
