6ca5b2053a Auto merge of #4478 - tsurai:master, r=flip1995 
Fix incorrect swap suggestion

Clippy suggests using swap on fields belonging to the same owner causing two mutable borrows of the owner.

Disclosure: This is my first time working with clippy and rusts HIR. I'm very grateful for assistance and suggestions to improve the PR.

fixes #981

8af4e09605 Auto merge of #4458 - flip1995:block_in_if_ext_macro, r=phansch 
Allow block_in_if_{stmt,expr} in external macro

I found this by running `cargo fix --clippy` on quite a big codebase.

You could refactor this assert to
```rust
let block_expr = _;
assert!(block_expr);
```

but,
1. it doesn't increase the readability IMO
2. That isn't possible in a `debug_assert!`

I'm not sure though, if we should allow this for macros in general or just for external macros.
