aarch64: turn off jump table optimization during jit compilation
aarch64: turn off jump table optimization during jit compilation

test_clang.py: test_jump_table will get failed with error messgae:
bpf: Failed to load program: Invalid argument
unknown opcode a0
processed 0 insns (limit 1000000) max_states_per_insn 0 total_states 0
peak_states 0 mark_read 0

HINT: The 'unknown opcode' can happen if you reference a global or
static variable, or data in read-only section. For example, 'char *p =
"hello"' will result in p referencing a read-only section, and 'char p[]
= "hello"' will have "hello" stored on the stack.
