[PATCH v1 1/10] Move Macro W to insn.h

[Srikar Dronamraju <srikar@linux.vnet.ibm.com>]

Move Macro W to asm/insn.h

Macro W used to know if the instructions are valid for
user-space/kernel space.  This macro is used by kprobes and
user_bkpt. (i.e user space breakpoint assistance layer.) So moving it
to a common header file asm/insn.h.
