gbe: add AtomicA64 instructions with stateless access

Graphics / Beignet - Luo Xionghu [intel.com] - 8 November 2016 06:38 UTC

add SEL_OP_ATOMICA64 for gen8 instruction selection and add ATOMICA64 for gen8 encoder accordingly, handle both simd8 and simd16 usage. for local type atomic, still use bti 254.

v2: remove useless code in stateless A64 atomic; add mising static address mode process; remove flag set since only dynamic address mode need it.
v3: add gen8_atomic_a64 field in Gen8NativeInstruction to be compatible with gen7_atomic_op.
