Add an unsized keyword which can be used on traits and trait bounds. It should be feature gated and we might change the keyword later (type has been suggested). We will compute the 'sized'-ness of every type and ensure compatibility of types.

Blocks #12938

Assigned to me.

auto merge of #13398 : nick29581/rust/unsized-enum, r=nikomatsakis
696f16e 
Now with proper checking of enums and allows unsized fields as the last field in a struct or variant. This PR only checks passing of unsized types and distinguishing them from sized ones. To be safe we also need to control storage.

Closes issues #12969 and #13121, supersedes #13375 (all the discussion there is valid here too).

Yes, it is (although we are going with a totally different syntax which is still to do)
