auto merge of #13295 : huonw/rust/gate-concat-idents, r=alexcrichton

Browse source 
rustc: feature-gate `concat_idents!`.

concat_idents! is not as useful as it could be, due to macros only being
allowed in limited places, and hygiene, so lets feature gate it until we
make a decision about it.

cc #13294
