Move instruction decoding into new arch/ directory
This patch moves the following functions into the arch/ common
directory, in new files arch/aarch64-insn.{h,c}. They are prefixed with
'aarch64_':
- aarch64_decode_adrp
- aarch64_decode_b
- aarch64_decode_cb
- aarch64_decode_tb
We will need them to implement fast tracepoints in GDBserver.
For consistency, this patch also adds the 'aarch64_' prefix to static
decoding functions that do not need to be shared right now.
V2:
make sure the formatting issues propagated
fix `gdbserver/configure.srv'.
