Support displaced stepping in aarch64-linux
This patch is to support displaced stepping in aarch64-linux. A visitor is implemented for displaced stepping, and used to record information to fixup pc after displaced stepping if needed. Some emit_* functions are converted to macros, and moved to arch/aarch64-insn.{c,h} so that they can be shared. gdb: 2015-10-12 Yao Qi <yao.qi@linaro.org> * aarch64-linux-tdep.c: Include arch-utils.h. (aarch64_linux_init_abi): Call set_gdbarch_max_insn_length, set_gdbarch_displaced_step_copy_insn, set_gdbarch_displaced_step_fixup, set_gdbarch_displaced_step_free_closure, set_gdbarch_displaced_step_location, and set_gdbarch_displaced_step_hw_singlestep. * aarch64-tdep.c (struct displaced_step_closure): New.
