[PATCH 0/4 V6] Process record and reverse debugging support on aarch64-linux

[Yao Qi <qiyaoltc@gmail.com>]

This patch series is about adding process recording and reverse
debugging for aarch64-linux target.

This is V6, with some changes on top of V5
https://sourceware.org/ml/gdb-patches/2015-05/msg00239.html
with some changes,

 - Indent the code, and fix some format issues,
 - Fix one bug about handling SIMD instructions,
 - Always record register CPSR [1]
 - Pick up a small set of instructions from Omair's test in the my
   test case,
 - Complete changelog and commit log message.

There are 7 fails in gdb.reverse, shown in the commit log of patch
#3, which are not related to instruction decoding and recording for
aarch64.

[1] aarch64 doesn't have CPSR register, which only exist on ARM or
aarch32 state.  In aarch64, linux kernel ptrace interface exposes
64-bit PSTATE rather than CPSR register.  PSTATE may be changed
during the execution of instructions, for example, after
single step.  In process record, we have to always record CPSR.
I plan to replace CPSR with PSTATE in aarch64 separately.
