Fix rustc breaking change: convert to Place's new boxed slice projection
Addressed breaking changes from rust-lang PR https://github.com/rust-lang/rust/pull/63420/
I'm not entirely sure the semantics are preserved as I don't have much knowledge about MIR yet. So this code was largely reverse-engineered from the PR above. I wouldn't be surprised if I did something wrong :).
I followed the instructions to pull latest rustc from master and verified the build break I was seeing in my PR for cast-lossless in Travis CI. With these changes, it compiles again and all tests pass.

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
changelog: Fix false positive in `manual_swap` lint
New `is_integer_const` to check more const ints
This mostly affects loop checks and the modulo_one lint. Tests were also updated where applicable.
changelog: none
Changed more `Vec` paths to diagnostic_items
In #4519, I missed a few instances of path matching for `Vec`, so here they are.

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.

Stop using the HIR CFG
This does slightly change the behavior:
* Functions with unreachable code don't end up being ignored
* `match` guards are counted as +1 for each guard, rather than +1 for each pattern with a guard
* Or patterns don't add to the complexity

Simplify `utils::match_def_path`, removing a FIXME
changelog: none
This removes the `Vec<Symbol>` allocation. We still need to call `cx.get_def_path`, but this should already have been interned, and I don't see how we can keep ergonomics of that function without allocating a `Vec`.

Fix two occurences of TESTNAME=ui/foo_functions
changelog: Fix two occurrences of the wrong path to the foo_functions test in doc/adding_lints.md
This PR fixes the other two wrong paths to the example test. I already created a PR yesterday but only changed one. The old command was `TESTNAME=ui/foo_functions cargo uitest` and is now `TESTNAME=foo_functions cargo uitest`.
Remove ui/ from TESTNAME for foo lint example
changelog: Remove ui/ from TESTNAME in doc/adding-lints.md
This PR remove the `ui/` from the TESTNAME of the example foo lint in the 'Adding lints' documentation.
