Merge #1602
1602: Add check for recursive trait cycles r=philberty a=philberty
This adds a new RAII style TraitQueryGuard so that we can manage the query lifetime when resolving a trait. This adds in a DefId into a set when we begin to resolve and then finally removes it when completed. This allows us to add in a check at the start if this DefId is already within the set which means this is a trait cycle.
Fixes #1589
