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

[Eric Christopher]

Another possibility is that this gets mapped as a normal command line option passed into cc1 and then it can just be a subtarget feature?

Idle thoughts of different implementation, but it avoids a lot of complication and per-target free form attributes.
