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. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
