Updates for arm64 eBPF JIT. The main addition here is implementation of bpf_tail_call.
#1: Fix missing header inclusion in linux/bpf.h. #2: Add bpf_tail_call for arm64. #3,4: Optimizations to reduce instruction count for jitted code. Changes since v1: - Added patch #1 to address build error due to missing header inclusion in linux/bpf.h. (Thanks to suggestion and ack by Daniel Borkmann) Ordered it ahead of bpf_tail_call patch #2 so build error is not triggered.
