[PATCH] Add Integer Saturation Intrinsics.

[Renato Golin]

My problem with implementing this on the ARM side is that the code won't be useful anywhere else.

Maybe, a better approach would be to have them just as special DAG nodes, created by a special DAG pass that only run for selected back-ends, instead of an IR intrisic, or an ARM-specific late pass.

I'm assuming the semantics of such pass would be very similar on other back-ends...
