[PATCH 00/11 v2] Split breakpoint_from_pc to breakpoint_kind_from_pc and sw_breakpoint_from_kind

[Yao Qi <qiyaoltc at gmail dot com>]

This patch series is to split gdbarch method breakpoint_from_pc to
methods breakpoint_kind_from_pc and sw_breakpoint_from_kind.  After
these changes, new gdbarch methods breakpoint_kind_from_pc and
sw_breakpoint_from_kind are more preferred than breakpoint_from_pc.

More details can be found in v1
https://sourceware.org/ml/gdb-patches/2016-08/msg00318.html there are
some changes compared with v1,

 - Rebase patch for recent mips changes,
 - Rename enum mips_breakpoint_kind,
 - Remove GDBARCH_BREAKPOINT_MANIPULATION and
   SET_GDBARCH_BREAKPOINT_MANIPULATION (patch #11),
 - Update comments to breakpoint_kind,
 - Fix typo,

Patches #1, #2, #5, #6, #7, #9 are not changed since v1.

This patch series are regression tested on x86_64-linux, arm-linux,
and aarch64-linux.
