Add `ConstraintCategory::Usage` for handling aggregate construction In some cases, we emit borrowcheck diagnostics pointing at a particular field expression in a struct expression (e.g. `MyStruct { field: my_expr }`). However, this behavior currently relies on us choosing the `ConstraintCategory::Boring` with the 'correct' span. When adding additional variants to `ConstraintCategory`, (or changing existing usages away from `ConstraintCategory::Boring`), the current behavior can easily get broken, since a non-boring constraint will get chosen over a boring one. To make the diagnostic output less fragile, this commit adds a `ConstraintCategory::Usage` variant. We use this variant for the temporary assignments created for each field of an aggregate we are constructing. Using this new variant, we can emit a message mentioning "this usage", emphasizing the fact that the error message is related to the specific use site (in the struct expression). This is preparation for additional work on improving NLL error messages (see #57374) 2021-09-06 21:59:24 +00:00			\| this usage requires that `x` is borrowed for `'static`
