ia64/pv_ops: paravirtualized instruction checker.

Browse Source 
This patch implements a checker to detect instructions which
should be paravirtualized instead of direct writing raw instruction.
This patch does rough check so that it doesn't fully cover all cases,
but it can detects most cases of paravirtualization breakage of hand
written assembly codes.
