ftrace: allow archs to preform pre and post process for code modification

This patch creates the weak functions: ftrace_arch_code_modify_prepare
and ftrace_arch_code_modify_post_process that are called before and
after the stop machine is called to modify the kernel text.

If the arch needs to do pre or post processing, it only needs to define
these functions.

[ Update: Ingo Molnar suggested using the name ftrace_arch_code_modify_*
          over using ftrace_arch_modify_* ]
