Auto merge of #48557 - matthewjasper:allow-trvial-bounds, r=nikomatsakis
Implement RFC 2056 trivial constraints in where clauses This is an implementation of the new behaviour for #48214. Tests are mostly updated to show the effects of this. Feature gate hasn't been added yet. Some things that are worth noting and are maybe not want we want * `&mut T: Copy` doesn't allow as much as someone might expect because there is often an implicit reborrow. * ~There isn't a check that a where clause is well-formed any more, so `where Vec<str>: Debug` is now allowed (without a `str: Sized` bound).~ r? @nikomatsakis
