Masami Hiramatsu 34e1ceb188 [IA64] kprobes: kprobe-booster for ia64 
Add kprobe-booster support on ia64.

Kprobe-booster improves the performance of kprobes by eliminating single-step,
where possible.  Currently, kprobe-booster is implemented on x86 and x86-64.
This is an ia64 port.

On ia64, kprobe-booster executes a copied bundle directly, instead of single
stepping.  Bundles which have B or X unit and which may cause an exception
(including break) are not executed directly.  And also, to prevent hitting
break exceptions on the copied bundle, only the hindmost kprobe is executed
directly if several kprobes share a bundle and are placed in different slots.
Note: set_brl_inst() is used for preparing an instruction buffer(it does not
modify any active code), so it does not need any atomic operation.
