Fixed by using unifyTargetFeatures. This makes sure the features are unique.

Fix issue about -mattr. Also use generic LTO option translation and use 
-plugin-opt.

I think StringRef will result in comparison by value. If we happen to have 
duplicate features, we may end up skipping a comma.
You need to either iterate ofer the pointers to elements of the Features, or 
use a different method of figuring out if a comma is necessary.
E.g. us a bool set at the end of the body.
