As emit_insn becomes extern, the prefix "aarch64_" is needed. This
patch renames emit_insn to aarch64_emit_insn.

* linux-aarch64-low.c: Update all callers of function renaming

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.

We will need to decode both ADR and ADRP instructions in GDBserver.
This patch makes common code handle both cases, even if GDB only needs
to decode the ADRP instruction.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_analyze_prologue): New is_adrp
variable. Call aarch64_decode_adr instead of
aarch64_decode_adrp.
* arch/aarch64-insn.h (aarch64_decode_adrp): Delete.
(aarch64_decode_adr): New function declaration.
* arch/aarch64-insn.c (aarch64_decode_adrp): Delete.
(aarch64_decode_adr): New function, factored out from
aarch64_decode_adrp to decode both adr and adrp instructions.
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'.
