aea490299f ARM: kprobes: Make str_pc_offset a constant on ARMv7 
The str_pc_offset value is architecturally defined on ARMv7 onwards so
we can make it a compile time constant. This means on Thumb kernels the
runtime checking code isn't needed, which saves us from having to fix it
to work for Thumb.

Move str_pc_offset into kprobes-common.c as it will be needed by common
code later.

0ab4c02dda ARM: kprobes: Add kprobes-common.c 
This file will contain the instruction decoding and emulation code
which is common to both ARM and Thumb instruction sets.

For now, we will just move over condition_checks from kprobes-arm.c
This table is also renamed to kprobe_condition_checks to avoid polluting
the public namespace with a too generic name.
