190589f8a7 Use structured suggestion for restricting bounds 
When a trait bound is not met and restricting a type parameter would
make the restriction hold, use a structured suggestion pointing at an
appropriate place (type param in param list or `where` clause).

Account for opaque parameters where instead of suggesting extending
the `where` clause, we suggest appending the new restriction:
`fn foo(impl Trait + UnmetTrait)`.

2a3969a3f7 Use new region infer errors for explaining borrows 
This gives at least some explanation for why a borrow is expected to
last for a certain free region. Also:

* Reports E0373: "closure may outlive the current function" with NLL.
* Special cases the case of returning a reference to (or value
  referencing) a local variable or temporary (E0515).
* Special case assigning a reference to a local variable in a closure
  to a captured variable.

Update output for borrowck=migrate compare mode. 
This commit updates the test output for the updated NLL compare mode
that uses `-Z borrowck=migrate` rather than `-Z borrowck=mir`. The
previous commit changes `compiletest` and this commit only updates
`.nll.stderr` files.

35a5541fd9 Auto merge of #53707 - eddyb:phantom-waffles, r=oli-obk 
rustc_typeck: turn `where Type:,` into a WF(Type) predicate, instead of ignoring it.

Fixes #53696, assuming crater doesn't catch anyone using this syntax already.

Allowing an empty list of bounds in the grammar was done for the benefit of macro authors, most of which would *probably* be using it for bounds on type parameters, which are always WF.
