This patch introdces 'checker' to decoding phase, and calls checkers
when instruction decoding. This allows further decoding for specific
instructions. This patch introduces a stub call of checkers in kprobe
arch_prepare_kprobe() as an example and for further expansion.

This doesn't correct any bugs when probing these instructions but makes
MOVW slightly faster and makes everything more symmetric with the Thumb
instruction cases.
We can also remove the now redundant PROBES_EMULATE_NONE and
PROBES_SIMULATE_NOP actions.

In discussion on LKML (https://lkml.org/lkml/2014/11/28/158), Russell
King suggests to move all probe related code to arch/arm/probes. This
patch does the work. Due to dependency on 'arch/arm/kernel/patch.h', this
patch also moves patch.h to 'arch/arm/include/asm/patch.h', and related
'#include' directives are also midified to '#include <asm/patch.h>'.
Following is an overview of this patch:
