IMPALA-9428 Add arm64 atomic ops
Atomic ops are implemented by asm.
Different arc have diffent implementation.
Here add arm64 atomic ops implementation.
The file atomicops-internals-arm64.h is originally from here:
https://github.com/protocolbuffers/protobuf/blob/3.5.x/src/google/protobuf/stubs/atomicops_internals_arm64_gcc.h
and the commit hash is ec021f5.
And I changed some instructions to newer version base
the original file, such as ldxr + memory barrier was
changed to ldaxr which has memory barrier natively.
And also added some funtions which impala use.
