[PATCH] Attach function attribute "arm-restrict-it" instead of passing arm-restrict-it as a backend-option

[Renato Golin]

I'm not too familiar with the Clang option parsing and LTO to make a judgement here, but from an ARM's point of view, this looks ok.

You're not seem to be testing the third state. You need some CHECK-NOT tests to make sure they won't come when you don't want them.
