[PATCH] Add Integer Saturation Intrinsics.

[Demikhovsky, Elena]

Hi,

I'm interested in these intrinsics for X86. Do you plan to push them as target independent?

Thanks.

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...
