2d90b91b5d auto merge of #19683 : nikomatsakis/rust/generalized-where-clauses, r=nrc 
This patch does not itself enable generalized where clauses, but it lays the groundwork. Rather than storing a list of bounds per type parameter, the trait selection and other logic is now driven by a unified list of predicates. All predicate handling is now driven through a common interface. This also fixes a number of bugs where region predicates were being dropped on the floor. As a drive-by, this patch also fixes some bugs in the opt-out-copy feature flag.

That said, this patch does not change the parser or AST in any way, so we still *generate* the list of predicates by walking a list of bounds (and we still *store* the bounds on the `TypeParameterDef` and so on). Those will get patched in a follow-up.

The commits in this case are standalone; the first few are simple refactorings.

9f492fefef Switch to using predicates to drive checking. Correct various tests -- 
in most cases, just the error message changed, but in some cases we
are reporting new errors that OUGHT to have been reported before but
we're overlooked (mostly involving the `'static` bound on `Send`).

ffc111889e auto merge of #19569 : murphm8/rust/ring_buf_insert, r=Gankro 
This is a first pass at insert on RingBuf. I tried to keep it as simple as possible. I'm not sure of the performance implications of doing one copy vs. copying multiple times but moving a smaller amount of memory. I chose to stick with one copy, even if the amount of memory I have to move is larger.

I believe this is part of #18424 

@Gankro mentioned this was missing.

d2e2bd1b44 auto merge of #19568 : barosl/rust/enum-struct-variants-ice, r=alexcrichton 
This pull request tries to fix #19340, which states two ICE cases related to enum struct variants.

It is my first attempt to fix the compiler. I found this solution by trial and error, so the method used to fix the issue looks very hacky. Please review it, and direct me to find a better solution.

I'm also to add test cases. Where should I put them? Maybe `src/test/run-pass/issue-19340.rs`?

da83ad8e2c auto merge of #19514 : jbranchaud/rust/add-btree-set-bitor, r=Gankro 
I am trying to add an implementation of `bitor` for `BTreeSet`. I think I am most of the way there, but I am going to need some guidance to take it all the way.

When I run `make check`, I get:

```
error: cannot move out of dereference of `&`-pointer
self.union(_rhs).map(|&i| i).collect::<BTreeSet<T>>()
                      ^~
```

I'd appreciate any nudges in the right direction. If I can figure this one out, I am sure I will be able to implement `bitand`, `bitxor`, and `sub` as well.

/cc @Gankro 

---

**Update**

I have added implementations for `BitOr`, `BitAnd`, `BitXor`, and `Sub` for `BTreeSet`.
